Abstract

A data transaction processing system in which transaction data is entered by the user in response to prompts in a template which is tailored to each user application. The template and entered data are accumulated into data transactions which are immediately transmitted upon completion to an external database server for processing and storage. The data transactions are not locally stored for processing, and no conventional operating system is necessary. No local processing needs to be provided, and the only local storage is flash PROM which stored the control firmware, a flash memory which stores the data streams making up the forms and menus, and a small RAM which operates as an input/output transaction buffer for storing the data streams of the template and the user replies to the prompts during assembly of a data transaction. The data transaction is received via standard protocols at a database server which, depending upon the application, stores the entire data transaction, explodes the data transaction to produce ancillary records which are then stored, and/or forwards the data transaction or some or all of the ancillary records to other database servers for updating other databases associated with those database servers. Also, in response to requests from the transaction entry device, the database server may return data streams for use in completing the fields in the data transaction or in presenting a menu on the display which was read in from the database server or a remote phone mail system. The transaction entry device is integrated with a telephone and is accessed via a touch screen, an optional keyboard, a magnetic card reader, voice entry, a modem, and the like.

BACKGROUND OF THE INVENTION
• 1. Field of the Invention
• The present invention relates to a system for automatically capturing data at the point of transaction and storing that data in the appropriate database(s), and more particularly, to a data transaction processing system including a transaction entry device which can selectively operate in a telephone mode and a transaction entry mode. In the telephone mode, the transaction entry device operates as a conventional telephone. However, in the transaction entry mode, menus are used to navigate the user to forms which facilitate the entry of data. The entered data and forms together form data transactions which are transmitted to one or more databases for processing and storage. The database(s) also “explodes” the data transactions into their component parts and transmits those component parts to still other databases for processing and storage so that the data in the data transactions automatically updates all current database items affected by such data.
• 2. Description of the Prior Art
• The telephone has become an increasingly versatile instrument. The functionality of telephones has been expanded by incorporating the functions of answering machines, facsimile machines, and the like. Point-of-entry systems have also been developed which incorporate computer processing capabilities into conventional telephones. For example, a computer/telephone apparatus is described in U.S. Pat. Nos. 5,195,130, 5,008,927, and 4,991,199 which configures a telephone as a programmable microcomputer which is operated through the standard telephone 12-key keypad. A programmable gate array is reconfigured to accommodate various types of software which require different hardware configurations but without actually reconfiguring the hardware. The reconfiguration data is received from a network host computer and is used by the programmable microcomputer to emulate the hardware of any of a plurality of service bureaus which communicate with the network host computer. In this manner, the telephone/computer is configured to communicate data to/from any of a number of different service bureaus via conventional telephone lines.
• However, telephone/computer systems of the type described in the afore-mentioned patents are typically quite complicated and expensive and are limited by the types of operating software which can be downloaded from the network host computer. Also, such telephone/computer systems are relatively slow since the microcomputer must be reconfigured before it will permit communication with the requested service bureau. Because of these characteristic features, such telephone/computer systems are typically used in public locations and are not efficient for creating point-of-entry transactions in typical commercial or private settings. A point-of-entry transaction system is desired which does not have such limitations and which is operating system independent.
• Elimination of the requirement of a conventional operating system and the associated application programs for the microcomputer of a data entry device would greatly decrease the cost of such a device. However, to date, this has not been possible because the operating system is needed to run the application programs which control the data communications and together handle discrete parts of the system. Unfortunately, such application programs require substantial amounts of local memory and substantial processing power for performing the desired functions. Also, the operating systems themselves tend to be quite costly to purchase and maintain.
• Accordingly, a data entry system is desired which does not have the inherent limitations of conventional point-of-entry systems such as the requirement of a standard operating system for communication with a remote service bureau or file server. A data entry device and associated system is desired which performs a minimal amount of processing at the data entry device so that the data entry device may be as simple and inexpensive as possible, thereby bringing the cost of such a device into a range suitable for most commercial and private uses. It is also preferable that such a data entry device provide a wide range of functionality without requiring a local operating system program and a plurality of applications programs for implementing each function. The present invention has been designed to meet these needs.
SUMMARY OF THE INVENTION
• The system which meets the above-mentioned needs in the art includes a transaction entry device that permits the user to organize and control all aspects of his or her personal transactions as well as any transactions that may occur in an office setting. In its simplest terms, the transaction entry device formats input data into a data transaction having content which is dependent upon the type of application to which the associated data pertains. These data transactions are then transferred to a local or remote database server which “explodes” each data transaction into its component parts for updating all databases containing data to which the data in the component parts pertain. In this “transaction entry mode” the transaction entry device of the invention functions as a multi-purpose workstation. However, since the data transactions are created without the use of an operating system or application programs, the transaction entry device is quite simple and inexpensive and may be readily integrated with the customer's desktop telephone or portable telephone.
• The present invention combines computer technology and telephone technology to allow transaction data to be captured at the point of initiation of the transaction. The transaction entry device is integrated into a conventional telephone which acts as either a normal telephone in a telephone mode or as a transaction entry device in a transaction entry mode. When in telephone mode, the telephone operates in a conventional manner. However, when in transaction entry mode, the transaction entry device is driven by a microprocessor which is, in turn, driven by an operating system independent transaction assembly (or application) server (TAS) comprised of data streams stored in a flash PROM. The TAS is absolutely self-contained in its relationship to the hardware of the transaction entry device and in general performs the two basic functions of (1) generating a template or form from a data stream and (2) developing a data transaction as the user inputs data in response to prompts in the template or form. The template is a series of data streams read from a local flash memory or transmitted directly from an external source such as a database file server.
• During operation, the data entered by the user in response to prompts in the template are accumulated into data transactions which are immediately transmitted to an external database server. Unlike typical prior art systems, the data transactions are not locally stored for processing by the local microprocessor once the data transaction has been completed. On the contrary, the only required storage in the transaction entry device is a flash PROM for storing the TAS firmware, a flash memory for storing the data streams used by the TAS firmware to complete a form and the modem numbers for the remote database servers, and a small RAM which operates as an input/output transaction buffer for storing the data streams of the template and the user replies to the prompts in the template during assembly of a data transaction. The transaction buffer(s) only needs to be as large as the largest data transaction since it only stores the form until the entire data transaction is completed. In this sense, the transaction entry device serves as an assembly point for specific transactions until they are ready for transmission to an external database server for processing and storage.
• The data transaction formed by the transaction entry device is transmitted via modem to a local or remote database server for processing and storage. The data transaction is received via standard protocols at the database server which, depending upon the application, stores the entire data transaction, explodes the data transaction to produce ancillary records which are then stored, and/or forwards the data transaction or some or all of the ancillary records to other database servers for updating other databases associated with those database servers. Also, in response to requests from the transaction entry device, any of the database servers may send data streams back to the transaction entry device for use in completing the fields in the data transaction or in displaying new forms or menus for selection.
• Thus, the data transaction system of the invention comprises at least three tiers: a first tier for capturing the data transaction from the user, where the data transaction has a one-to-many relationship to file structures; a second tier for exploding the data transaction into its component parts on a system-specific basis so that each component part has a one-to-one correspondence with a file; and a third tier for providing additional explosions of the data transactions on an application-specific basis so that each application has its own set of data transactions.
• A preferred embodiment of the transaction entry device of the invention resembles a conventional telephone except that it includes a touch screen and an optional keyboard for data entry in addition to the conventional numeric and function keypad inputs. A telephone handset or headset is optional and may be replaced by a microphone and speaker. The transaction entry device of the invention also includes RS-232 and other input/output ports for accommodating other options such as a wireless (RF) receiver, a magnetic card and/or smart card reader, a video camera and video display, infrared controllers, and the like. The telephone preferably has normal touch-tone functions as well as mobile and cellular options.
• Preferably, the transaction entry device contains a microprocessor such as an Intel 80386SX or higher, one megabyte of flash memory for dynamically storing the data streams for the templates, one megabyte of flash PROM for storing the TAS firmware, and a 128 kB RAM which functions as a transaction buffer for storing the data streams of the templates and the user responses until completion of the data transaction. A graphics display screen is also provided for displaying the templates to the user for the entry of the data which will form the data transactions. Preferably, the graphics display screen is on the order of 24 lines by 40 characters for a desktop unit and 12 lines by 40 characters for a cellular unit.
• The transaction assembly (application) server (TAS) guides the user to the desired template via menu selections, where the menus and templates are stored in flash memory as data streams and are called up by the TAS firmware when selected by the user. Generally, the menus are treated as a special type of template or form. The templates stored in the flash memory may be updated at any time to handle particular applications by reading in a new data set which has been created off-line and downloaded via modem or direct connection to the flash memory of the transaction entry device. Alternatively, the data may be downloaded to an RS-232 input. The same connections may be used to provide an automatic read from a remote database or an automatic write to a remote database. New applications may be added simply by adding additional flash memory elements containing the necessary templates for the new application.
• The telephone/transaction entry device and the associated system for storing transaction data in accordance with the invention is unique in that it separates the user from the database and provides a simple, user friendly way to enter transaction data without requiring a local operating system to run various application programs. Since all data is entered as data transactions determined by templates tailored to particular applications, the user applications may be generalized so that no unique user application programs need to be written when a new application is added. However, if code is needed, or if a multimedia element is to be included in a data transaction, it can be appended to a data transaction as an additional parameter stream in the stream of data forming the data transaction. Also, since the nature of the data in the respective fields of the templates for particular applications is known in advance, the interface to a database server to permit storage of the data transactions and their component parts in the appropriate databases in the appropriate formats for each database becomes trivial.
• In an alternative implementation of the invention, a process may be selected from the menu of the transaction entry device which creates a “visible” menu corresponding to a voice mail menu of a remote phone mail system. When such a process is selected, the telephone or modem interface makes a telephone connection to the remote phone mail system, and, once the connection is made, the data transaction assembler sends a data request for a visual representation of the phone mail menu of the remote phone mail system via the telephone connection to the remote phone mail system. A data stream containing the visual representation of the phone mail menu from the remote phone mail system is then returned via the telephone connection and stored in a memory of the transaction entry device for presentation to the display screen of thetransaction entry device12. When the desired phone mail menu option is selected from the “visible” voice mail menu, the data transaction assembler creates a data transaction indicating which menu item was selected and sends the data transaction to the remote phone mail system via the telephone connection. Based on the menu selection, the remote phone mail system then returns a data stream containing a visual representation of the next phone mail menu via the telephone connection for storage and display. This process is repeated until the calling party is required to leave a message or the called party is reached.

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENT
• A system and method which meets the above-mentioned objects and provides other beneficial features in accordance with the presently preferred exemplary embodiment of the invention will be described below with reference toFIGS. 1-10. Those skilled in the art will readily appreciate that the description given herein with respect to those figures is for explanatory purposes only and is not intended in any way to limit the scope of the invention. For example, those skilled in the art will appreciate that the telephone/transaction entry device and system for entering data transactions into remote databases in accordance with the invention may be used in numerous settings in numerous applications. Accordingly, all questions regarding the scope of the invention should be resolved by referring to the claims.
A. System Description1. Overview
• The system of the invention provides for the automatic capture and computerization of data associated with data transactions as they occur. As used herein, a data transaction is the combination of a form or template or a series of forms or templates containing data entry prompts and the data entered in response to those prompts. Throughout the remainder of this specification, the words “form” and “template” will be used interchangeably.
• The data transactions are generated by a transaction entry device through an interactive process between the user and the form. The data transaction is assembled in a transaction buffer in the data transaction entry device and then transmitted to an external database for storage. No local storage for data transactions is available. The data transaction is defined externally by the database in that all applications consist of a series of customized forms and prompts for soliciting entry of the data needed to update the databases containing data related to the particular application. Generally, the data transaction will have a one-to-many relationship to the file structures of the database containing data for that application.
• The data transactions are entered using the transaction entry device. Preferably, the transaction entry device is integrated with telephone electronics so that the resulting device may selectively operate as a conventional telephone or as a data transaction entry device. The resulting transaction entry device preferably includes a touch screen and/or keyboard which provides input to a transaction assembly (application) server (TAS) which, in turn, presents selection options via menus and forms for completion by the user. Menu and form selection and form completion is made by touch, by key selection from the keyboard, by moving a cursor to the appropriate selection point and depressing a key, or even by voice command. Whenever data entry (other than mere selection) is desired, it is accomplished via a menu-driven selection process and/or by direct entry of data using a keyboard, a keypad, a touch screen, and the like. In the menu-driven case, a set of options is presented to the display screen by the TAS firmware. If this set of options exceeds the capacity of the display screen, then the list is scrolled up or down through the use of scroll keys on the device, by voice command, or by touch at scroll command points. Once the selection is made, the data associated with that selection is automatically entered into the form from a local or remote database, or the data is input by the user. In the event of keyboard entry, the TAS firmware may present a keyboard at the bottom of the display screen for touch entry; alternately, an optional keyboard located at the base of the transaction entry device may be used.
• When the data is entered independently of a selection process, such data also may be entered using a swipe card if the data resides on the swipe card or the data may be transferred into the data transaction via modem from an external source. The data read from the swipe card can be used to fill out a form or may be transmitted to an external database or computer. Data returned from the external database or computer via modem may also be used to fill out the fields in the form. As desired, the data in a data transaction may also be written to a swipe card or memory card and the like.
• The TAS firmware of the invention stores the options as well as control programs (microcode) for the processor for use with the templates in creating the data transactions. The TAS firmware also includes a program allowing connection via modem to one or more external computers and databases. Preferably, two modes of operation are available: transaction entry mode (with or without modem connection) and telephone mode. A selection of either the transaction entry mode or the telephone mode is made through a switch selection on the transaction entry device. When the transaction entry device is placed in the transaction entry mode, the TAS firmware immediately presents a selection menu for all of the options the system is programmed to handle. In the telephone mode, on the other hand, a dial tone is provided and the telephone keypad is enabled. In telephone mode, one or more lines may be connected so as to allow simultaneous use of the transaction entry device without interfering with the modem connection. However, if a single telephone line is used, the telephone capability is available at all times or intermittently via modem as specified by the particular application. In the intermittent mode, upon a “save” the transaction entry device will control a dial up and transfer of data to a remote database server. On the other hand, if the telephone is used with an automatic dialer mechanism utilizing a phone list, the transaction entry device may automatically change from the telephone mode to the transaction entry mode. In this case, a display on the telephone may be used to present a name and telephone list from which a selection can be made in accordance with the menu selection techniques described below.
2. Data Transaction System (FIGS.1-4)
• FIG. 1 is a schematic diagram of asystem10 for entering data transactions into databases in accordance with the invention. As illustrated,system10 comprises a first tier for capturing a data transaction having a one-to-many relationship to file structures, a second tier for exploding the data transaction into component parts having a one-to-one relationship to file structures, and a third tier for providing additional explosion of the data transactions for specific applications.
• The first tier comprises atransaction entry device12 which captures the data transaction from the user in response to any of a plurality of inputs from the user.Transaction entry device12 includesconventional telephone electronics14 andspeaker16 and adata transaction assembler18 for creating a data transaction in accordance with the invention. Adisplay screen20 is preferably associated withdata transaction assembler18 so that the user may monitor creation of each data transaction.Telephone electronics14 are connected to atelephone switching network22 via aconventional voice connection24 over the telephone lines, whiledata transaction assembler18 is connected viatelephone lines26 to one ormore database servers28. As illustrated inFIG. 1,telephone lines24 and26 may be separate lines, thereby permitting simultaneous use of the telephone and data entry functions, or thetelephone electronics14 anddata transaction assembler18 may be connected to a single line as illustrated in phantom inFIG. 1. Of course, when thetelephone electronics14 anddata transaction assembler18 are connected to a single line, a mode switch will enable their mutually exclusive operation, or alternatively, any of a number of conventional transmission schemes may be used to permit simultaneous transmission of the voice from thetelephone electronics14 and the data from thedata transaction assembler18 over the same line.
• During operation in the transaction entry mode,transaction entry device12 is responsive to user input devices such as a touch screen, a telephone keypad, a keyboard, a usingdata transaction assembler18. Alternatively, thetransaction entry device12 operates in a telephone mode as a conventional telephone and receives inputs from a microphone and/or a handset, a touch tone keypad, and the like. More details of thetransaction entry device12 anddata transaction assembler18 will be provided in the next section with respect toFIGS. 5-10.
• The second tier comprises one ormore database servers28 and their associateddatabases30. In general, eachdatabase server28 receives data transactions from one or moretransaction entry devices12 and “explodes” the received data transactions into their component parts for storage in the appropriate files of the associateddatabase30. In other words, the one-to-many file structure of the data transactions from one or moretransaction entry devices12 is converted into many one-to-one data transactions for storage in individual files ofdatabase30.
• Eachdatabase server28 includes amodem32 for transmitting/receiving data from thetelephone lines26, particularly the data transactions from one or moretransaction entry devices12. Preferably, the data transactions are transmitted over thetelephone lines26 as data packets having, for example, 128 bytes, where 120 bytes contain information- and 8 bytes contain control data. Atransaction queue34 acts as an input buffer for the received data transactions and controls the rate of presentation of the data transactions totransaction controller36.Transaction controller36 processes the received data transactions to extract the physical file relationships of the component parts of the data transactions and stores the components parts and different combinations thereof in the appropriate files of associateddatabase30. Alternatively,transaction controller36 may process a data request fromdata transaction assembler18 requesting information fromdatabase30 for completing certain fields of a data transaction being processed by thetransaction entry device12.Database30 then provides the requested information todatabase server28 which, viamodem32, provides a data stream back todata transaction assembler18 for use in completing the data transactions or presenting additional menus and forms in accordance with the invention. Typically, a user ID and password are transmitted to thetransaction controller36 to permit a connection to be made bydata transaction assembler18. Thus,transaction controller36 also checks and stores startup and logoff information in addition to storing data transactions and directing reconstituted data transactions to other database servers as described herein. In addition,database server28 may include a conventional phone mail system with an associated database for storing voice mail messages. In this case, the data transaction may include voice data for storage in the remote voice mail system.
• As shown inFIG. 1,several database servers28 may be provided. Preferably, eachtransaction entry device12 has an associateddatabase server28 for performing any desired processing of its data transactions, although it is preferred that the data transactions be copied to at least oneother database server28 as shown inFIG. 1. This redundancy minimizes the possibility of losing data in the event of a power outage and the like. Preferably, eachdatabase server28 contains essentially the same hardware, althoughmodem32,transaction queue34, andtransaction controller36 have not been shown for alldatabase servers28 for ease of illustration.
• In transaction entry mode, thedata transaction assembler18 oftransaction entry device12 creates a data transaction that is transmitted to an associatedtransaction controller36 of an associateddatabase server28. By “associated” it is meant that thedatabase server28 functions to perform any processing requested or necessary in conjunction with the storage of a data transaction from a particulartransaction entry device12. Of course, aparticular database server28 may have severaltransaction entry devices12 associated with it. So that no data will be lost, aparticular database server28 may also serve as a backup for anotherdatabase server28 in the event of the failure of anydatabase server28.
• As will be explained in more detail below with respect toFIGS. 2-4,database server28 “explodes” data transactions received fromdata transaction assembler18 and provides the component parts of the “exploded” file dependent data transactions viamodem32 toother database servers28 as necessary to update other databases. Alternatively, as shown by dotted line inFIG. 1, the “explosion” of the data transactions may be performed by thedata transaction assembler18 at thetransaction entry device12 and the component parts transmitted to allappropriate databases28 for updating the data therein. For this purpose, thedata transaction assembler18 will also need to know the modem numbers for alldatabase servers28 to be updated by the exploded data transactions. However, those skilled in the art will appreciate that this latter alternative will require access to numerous phone lines by the transaction entry device and that such phone lines are not always available to the user.
• Finally, the third tier of thesystem10 includesadditional database servers38 anddatabases40 which support file dependent data transactions for specific applications. This additional tier ofdatabase servers38 anddatabases40 permits the data in the data transactions to be routed to application specific databases for storage of application specific data and access by thosetransaction entry devices12 requesting data related to that specific application.
• The creation and storage of a data transaction in accordance with the invention will now be described with respect toFIGS. 2-4.
• Data transactions are created bydata transaction assembler18 as a data stream of a known format. A generic data transaction is illustrated inFIG. 2. As defined herein, a data transaction is created using a form containing one or more of the following: instructions, prompts, menu selection options, and a template with fields for data entry. Generally, the menu form consists of prompts for selecting a form, another menu, or a process, and a single slot for entering a selection, while the date entry form consists of prompts and instructions together with fields for entering data as shown inFIG. 2. The data entry form can have either single or multiple fields for entering data.
• In transaction entry mode, the user navigates through menus ofdata transaction assembler18 until a form related to a particular type of data entry operation is selected. Once selected,data transaction form42 is presented to the user ondisplay device20. Thedata transaction form42 is a collection of data defining the visual presentation on thedisplay device20 and a list of the fields through which linkages to external database files are defined.
• As shown inFIG. 2,data transaction form42 includes aformat field44 which identifies the type of data transaction this form pertains to, the length of the form, the number of pages in the form, the number of bytes in each field, storage keys, and the like. The body of thedata transaction form42 comprises a predetermined series ofprompts46 which are provided to thedisplay screen20 as a data stream. The prompts preferably include descriptive data which may be alphanumeric, an icon, or a list that scrolls, if necessary.Fields48 are blank spaces of predetermined size provided for accepting user input in response to each prompt. Generally, the size of eachfield48 is also stored in the stream of data defining thedata transaction form42. Since the prompts are tailored to elicit the necessary data for the application for which thedata transaction form42 was created, thefields48 will include the user data necessary for processing a data transaction for that particular type of application. The user responses become part of the data stream which forms the data transaction. Typically, thedata transaction form42 also includes amiscellaneous processing field50 which permits processing data unique to that form to be appended to the data transaction for transmission. Such processing data may include, for example, equations which define the relationships of the data in certain fields of the data transaction or audio or video data attached to a multimedia data transaction. In addition, non-display data associated with the time of data entry, the date of data entry, the user ID, and the like may be stored inmiscellaneous processing field50.
• FIGS. 3 and 4 illustrate the “explosion” of the stream of data forming the data transaction created using thedata transaction form42 ofFIG. 2. As shown inFIG. 3, each data transaction contains data which is specific to a particular database and/or specific to particular files in one or more databases. The data in the data transaction is “exploded” accordingly. For example, the complete data transaction fromFIG. 2 (Form A) is stored in a particular file (file 110) of the database associated with thetransaction entry device12 which created the data transaction (database11 inFIG. 1). Storage of the entire data transaction is desired so that records may be maintained in the event of system error, power failure, and the like. Thetransaction controller36 then extracts data from those fields of the data transaction which it knows to be related in forms of that particular type. For example, the data infields1,2,6,10, and a function of the data infield11 may relate to a particular application stored infile 111 ofdatabase11. Similarly, the data infields3,6,10,12, and14 may be related to an application stored infile 112 ofdatabase11, while the data infields1,2,7,8,9, and a function of the data infields10,11, and12 may be related to an application stored in file 113 ofdatabase11. These fields are extracted from the received data transaction bytransaction controller36, reconstituted into a file entry of the appropriate format (as necessary), and stored in the associateddatabase30.
• All of the data in the received data transaction, or a subset thereof, may also be retransmitted to one or more additional application specific databases, such asdatabase21 of thedatabases40 intier 3. As illustrated inFIG. 3, the database specific data offields1,4,5,13, and14, forming the subset (Form B) of the original transaction (Form A), is stored infile 210 ofdatabase21 so that a complete record may be maintained. Subsets of the data in Form B are then stored in specific files ofdatabase21 as indicated. In this manner, the data of the original data transaction (Form A) is automatically sent to all databases which contain files which must be updated by any or all of the data in Form A.
• FIG. 4 illustrates the explosion of the data transaction in Figure for thesystem10 illustrated inFIG. 1. As shown, the data in the data transaction (Form A) is extracted to update files 110-113 ofdatabase11 as well as files 210-212 ofdatabase21. A redundant copy of Form A is also maintained indatabase12.
• As will be explained more fully below, the system ofFIGS. 1-4 is significant in that the data in a data transaction may update one or more databases serviced by file servers operating under control of numerous types of operating systems without the requirement of a terminal or operating system emulation by thetransaction entry device12. On the contrary, thetransaction entry device12 of the invention permits data capture and storage with a minimum amount of processing at the transaction entry point (tier 1), which, of course, minimizes system cost.
B. Transaction Entry Device12 (FIGS.5-10)
• As noted above, thetransaction entry device12 is particularly characterized by thedata transaction assembler18, which controls the various operations of thetransaction entry device12 in its transaction entry mode. Preferably,data transaction assembler18 uses simple menu structures and predetermined forms stored as data streams in a flash memory for facilitating data entry. The menus are treated as a special type of form and are used to call other menus, forms, or processes. The forms, on the other hand, are used to create data transactions which are sent to one or more file servers operating under different operating systems, where the data transaction is “exploded” into its component parts for storage in a unique file structure for updating all records affected by the data in that data transaction. In turn, the “exploded” data transactions may be transmitted to another application specific database (tier 3) for storage. Processes, on the other hand, are selected to perform limited processing of the values in the fields of the forms. Such processing may be performed locally but is preferably performed by the associateddatabase server28.

• A preferred embodiment of atransaction entry device2 incorporated into a conventional telephone is illustrated inFIGS. 5 and 6. As shown inFIG. 5a, a preferred desktop embodiment of atransaction entry device12 includes ahousing52 on the order of 8 inches wide by 12 inches long forhousing telephone electronics14 and the hardware ofdata transaction assembler18.Transaction entry device12 includes an optional handset (or headset)54, cradle56 (FIG. 5b),numeric keypad58, telephone function/line keys60,microphone62, andspeaker16, which facilitate operation of the transaction entry device in the telephone mode. As known to those skilled in the art, telephone functions accessed bytelephone function keys60 may include mute, speaker, line select, conference, hold, transfer, volume control, and the like.
• However, thetransaction entry device12 is further characterized bydisplay20 withtouch screen64, mode switch/computer function keys66, optionalretractable keyboard68, and optional magnetic/smart card reader70, which facilitate operation of thetransaction entry device12 in the transaction entry mode. A memory card reader may also be accessed via a door (not shown) as in a laptop computer. Preferably,display20 is a super twisted, high contrast, reflective liquid crystal display (LCD) with a minimum of 20 characters per line and 16 lines (preferably, 40 columns by 24 lines), whiletouch screen64 is preferably a clear pressure sensitive keyboard made up of 224 keys (16 rows of 14 keys) attached to the face of the LCD. Preferably, the LCD is also available as a backlit unit. Of course,touch screen64 is not necessary ifoptional keyboard68 is provided. In addition, a battery backup71 (FIG. 6) may also be provided; alternatively, thebattery71 may be the primary power source for a portable (cellular) embodiment of thetransaction entry device12 in accordance with the invention.
• FIG. 5billustrates several of the connections totransaction entry device12. Typically,transaction entry device12 includes a handset (headset)jack72 for connecting optional handset (headset)54 totelephone electronics14 when it is desired to communicate more privately than whenonly microphone62 andspeaker16 are used. Avideo input port74 is also provided for connecting conventionaldata compression circuitry75 within the transaction entry device12 (FIG. 6) to an optional video camera which provides picture phone type video or to a facsimile device or scanner. Such video data may be appended a frame at a time to the end of a data transaction inmiscellaneous processing field50 to create a multimedia data transaction as described above with respect toFIG. 2. Avideo output port76 is also provided for providing decompressed video or facsimile data from data decompression circuit77 (FIG. 6) to a video receiver, a high quality computer monitor, a facsimile device, and the like. Such data may also be provided toprinter port82 or84 as desired. A multi-line phone jack (modem interface)78 is also provided. Preferably,modem interface78 provides separate modem connections for thetelephone electronics14 and thedata transaction assembler18, although only a single modem connection is necessary.
• An optionalinfrared transceiver80 is further provided for enabling remote control operation of television and stereo equipment and the like in response to data transactions transmitted/received by thetransaction entry device12.Infrared transceiver80 includes an internal signal generator chip which reads parameters stored indata transaction assembler18 for determining the appropriate transmission frequencies for the infrared signals. Control of the infrared devices is then provided through menus on thedisplay20. Additionalinfrared transceivers80 may also be provided on each corner of thehousing52 so that the infrared signal will cover more area (each transmitter typically covers about 60E circumference). All such devices are known to those skilled in the art and thus will not be described in detail here.
• A computer interface (RS-232)serial port82 andparallel port84 is also provided for transmitting/receiving data to/from another computer device and for providing output to a printer. Apower input port86 and akeyboard input88 are also provided.Keyboard input88 accepts a connection from a standard keyboard or a folding type keyboard (not shown) which may be used in addition to, or in place of,retractable keyboard68. Ari optional removable PCMCIA memory card interface89 (FIG. 6) for updating the operating instructions of thedata transaction assembler18 and an optional RF transceiver90 (Figure) for wireless networking to other electronic equipment may also be provided on thetransaction entry device12 as desired.
• FIG. 6 is a schematic diagram of the electronics of the transaction entry device illustrated inFIGS. 5(a) and5(b). Corresponding reference numerals for corresponding elements are used inFIGS. 5(a),5(b) and6. As shown inFIG. 6, in addition to the elements described above with respect toFIGS. 5(a) and5(b), thetransaction entry device12 may include a simplevoice recognition circuit91 which permits voice selection of menu options and the like. In “voice selection” mode, the user would voice “1”, “2” or “3” depending on the desired menu selection, and the voice would be picked up bymicrophone62 on thehousing52 of thetransaction entry device12 and recognized byvoice recognition circuitry91. The proper selection signal would then be sent to thedata transaction assembler18. Similarly, thedata transaction assembler18 may provide audible output using aconventional voice synthesizer92, which provides the audio output to the user viaspeaker16 and to a caller via modem interface/telephone line connection78. Thevoice synthesizer92 may, for example, allow certain data transactions to be audibilized for a blind person who cannot make selections from a conventional video display. In addition, avoice recorder93 may also be provided to record portions of telephone calls, portions of voiced data transactions, or a caller's message as when using a conventional digital answering machine. On the other hand,voice recorder93 may be provided indatabase server28 for use in storing/forwarding audible messages to thedatabase30.
• As noted above, thetransaction entry device12 is characterized bydata transaction assembler18, which controls the creation of data transactions in the transaction entry mode. As shown inFIG. 6,data transaction assembler18 is implemented in hardware using aconventional microprocessor94, such as an Intel 80386SX (20 MHz or higher) or equivalent, aTAS PROM95, a form/menu memory96, and a transaction buffer (RAM)97. In a preferred embodiment,TAS PROM95 is a flash PROM which holds 1 MB of control data (firmware) for the microprocessor94 (such as the microcode for the algorithms ofFIGS. 7-10 below), while form/menu memory96 is a flash memory which holds 1 MB of data transaction menus and forms.Transaction buffer97, on the other hand, only needs to be as large as the largest data transaction, and may hold, for example, up to 128 kB of transaction data including application and operating system variables. Preferably,TAS PROM95 and form/menu memory96 are updated by downloading data streams containing new instructions and/or forms and menus over aconventional data bus98 viamodem78,magnetic card interface70, or via a removable memory card read bymemory card interface89 as necessary. Alternatively, additional flash memory elements may be added as additional applications are added totransaction entry device12.Transaction buffer97 may also be expanded to handle transactions of any size or type, including multimedia applications in which video and/or audio data is appended to data transactions.
• Those skilled in the art will appreciate that thetransaction entry device12 may be docked into a docking station of a network.RF transceiver90 may be used for wireless communications in such an environment. In addition, those skilled in the art will appreciate that thetransaction entry device12 may be implemented as a battery operated portable device which is a cross between a laptop computer and a cellular telephone of the type illustrated by Paajanen et al. in U.S. Pat. No. 5,189,632, for example. In such an embodiment, an optional headpiece could be provided, as well as a microphone and speaker arrangement in the fliptop. Of course, the liquidcrystal display screen20 would typically be reduced in size to, for example, 40 columns by 12 rows, and thetouch screen64 may be eliminated. However, most of the other options of the embodiment ofFIGS. 5aand5bwould preferably remain so that the portable unit could also be used at a desk as desired. The electronics of thetransaction entry device12 would otherwise be as illustrated inFIG. 6 except for certain size and shape considerations well within the skill of those skilled in the art.
2. Software
• As will be apparent from the following description,data transaction assembler18 does not utilize a conventional operating system to control the operation ofmicroprocessor94. On the contrary,TAS PROM95 stores simple firmware algorithms (FIGS. 7-10) operating in a kernel fashion for navigating a user through menus and forms provided from form/menu memory96 for particular applications, and it is the resulting data streams which control themicroprocessor94 at any point in time. In other words, the data streams from theTAS PROM95 and the data streams from the form/menu memory96 together reconfiguremicroprocessor94 into a special purpose processor for each application specified by the forms. The microcode of theTAS PROM95 and the parameter streams from the form/menu memory96 thus operate together as a simple form driven operating system formicroprocessor94 for all applications and is the sole code used to control microprocessor94 (i.e., no conventional operating system or application programs are provided). As a result, themicroprocessor94 may be reconfigured into a new special purpose computer with each new form read from form/menu memory96, and such forms/menus may be added at any time by reading in the appropriate data streams from a memory card or from anexternal database server28 or by adding an additional PROM. A specific implementation of the TAS firmware stored inTAS PROM95 will be described below with respect toFIGS. 7-10.
• Thus, theTAS PROM95 contains control data (firmware) for themicroprocessor94 and resides in eachtransaction entry device12 for generating a template for a data transaction from a data stream stored in form/menu memory96 (or received directly from a memory card or external database server) and from data input by a user or retrieved from an external database or magnetic card, smart card, and the like. The TAS firmware and the selected template together control the behavior of themicroprocessor94 by logically defining a table of menu options and/or database interfaces which are navigated through by the user. As noted above, the user navigates through a series of menu selections by selecting another menu, a form, or a process. Once the data transaction for a desired application is completed, it is transmitted out for “explosion” into all of its component parts for storage. In this form, the TAS firmware fromTAS PROM95 and menus and forms from form/menu memory96 of the invention together replace a conventional operating system and individual application programs. Indeed, the invention permits thetransaction entry device12 to be completely operating system independent.
• Thedata transaction assembler18 of the invention is connected via a predetermined protocol stored as instructions withinTAS PROM95 to adatabase server28 and its associateddatabase30. As noted above, thedatabase server28 associated with a particulartransaction entry device12 operates as a repository of the data transactions created by thetransaction entry device12 and as a supplier of data to thetransaction entry device12 for completing the forms and providing additional forms, menus, processes, and the like. Since the system of the invention is operating system independent, there are no hardware or software limitations on the characteristics of thedatabase server28.
• The parameter set making up the individual forms are typically provided bydatabase server28 as a stream of data via modem and stored in form/menu memory96, while any downloaded instructions are stored inTAS PROM95. Linkage betweendata transaction assembler18 and itsdatabase server28 is preferably provided via a dictionary program specific to eachdatabase server28. This dictionary program knows the characteristics of each field of each form for each data transaction and is used by thedatabase server28 to “explode” the received data transactions into their component parts.
• Preferably, at power on,data transaction assembler18 automatically prompts the user with a “Download Parameter Streams” command so that the user can load into form/menu memory (flash memory)96 from an external source the desired streams of menu and form data for the desired application. The “download parameter” process will then be initiated by dialing theexternal database server28 initiating the connection via themodem interface78. Once connected, thetransaction controller36 ofdatabase server28 will transmit the requested parameter stream. Thedata transaction assembler18 will load the received data stream into form/menu memory96, and, upon completion, the prompt “Executive Menu Ready” will be presented on thedisplay screen20. The executive menu then will be automatically presented to the user for selection of the desired menu, form, or process.
• Upon initiation of the transaction entry mode by the user,data transaction assembler18 calls a set of panel parameters from form/menu memory96 and paints a form ontodisplay screen20. These forms are either menus for navigating to particular forms or a form into which data is entered by the user. As will be explained below, the menus provide functionality through simple menu selection. The form on thedisplay screen20 is completed by the user by entering the appropriate data usingtouch screen64 oroptional keyboard68. Alternatively, the requested data may be read in from a memory card viamemory card interface90, from a magnetic strip on a swipe card or smart card viamagnetic card interface70 ormemory card interface89, or voice input viavoice recognition circuit91. In addition, a request may be sent to thedatabase server28 associated with thetransaction entry device12 for data needed to populate certain fields in the present form. The type of data entry is requested from a subset of options presented to the user upon pressing a “?” key or a “Request for More Information” button. This request will give the user several options to choose from, such as dataentry using keyboard68,touch screen64, swipe card viamagnetic card interface70, memory card viamemory card interface89, by voice annunciation of the number of the item in the menu viavoice recognition circuit91, or via modem from adatabase30. Hence, the data transaction created by thedata transaction assembler18 may or may not make use of stored data for reducing the amount of data entry required of the user.
• When data entry option is selected,data transaction assembler18 does one of the following: another set of parameters is called up and another form is painted, the correctness of the selection is verified and a set of options for selections is presented based on interactions with stored data, the completed data transaction is transferred via modem todatabase server28 for storage indatabase30, or data values are requested fromdatabase30 for incorporation within thetransaction buffer97. In a preferred embodiment, selections from the menu are made by touching the appropriate place on the menu usingtouch screen64; by voice annunciation of the number of the menu item viamicrophone62 andvoice recognition circuit91; by using one of thecomputer function keys66 to run a cursor up the menu, another key to run the cursor down the menu, and a third key to make a selection in a conventional manner; or by usingkeyboard68 as a selection device. When thekeyboard68 is used, the keyboard keys may be used to control a cursor, with the “enter” key being used for making a selection; alternatively, the number of the item selected may be entered and the “enter” key pressed to make the selection. Once the selection is made, the appropriate form is extracted from form/menu memory96 as a stream of data.
• Alternatively, in addition to presenting a menu for selection or completing a form, thedata transaction assembler18 can also present a menu selection for initiating a process such as calculation of an interest rate using one or more fields in the form, the finding of a mean, the finding of a name, or searching for entries for a particular date. These processes may be stored inTAS PROM95, form/menu memory96, in an off-line server where they are initiated, or any other place where they may be loaded down to the operating portion of thetransaction entry device12. In a preferred embodiment, processes are generally initiated in thedatabase server28 by sending a data request to thedatabase server28, processing the data in thedatabase server28, and then returning the answer as a data stream or report back to thetransaction entry device12.
• A process typically initiates a data string which calls a process on an external machine. For example, thetransaction entry device12 may be used to download and store control signals for infrared control of various devices using infrared transceiver80 (FIGS. 5 and 6). The form of the control signals will depend upon the signal storage in an optional infrared chip, which can be loaded by thedata transaction assembler18 or by an off-line device via modem or through the air usingRF transceiver90 for direct digital transfer in wireless form. In addition, in the case where thetransaction entry device12 is used in a medical office, for example, the process may be used to transmit a prescription to a pharmacy or mail order house using prestored modem numbers or may enable the physician to call up a list of phone calls to make for the day or a list of the followup appointments for a particular date. In other words, the TAS firmware can also “explode” the data transaction into all of its ancillary parts for transmission to numerous records in one or more databases.
• A preferred embodiment of the TAS firmware will now be described with respect toFIGS. 7-10.
• As noted above, the transaction assembly (application) server (TAS) is a data stream stored inTAS PROM95 which together with the forms from form/menu memory96 create a simple form driven operating system which provides the necessary control data (firmware) tomicroprocessor94 so that no conventional operating system is necessary.FIG. 7 is a flow diagram of a menu driven TAS in accordance with a preferred embodiment of the invention. As illustrated, the TAS firmware starts atstep100 and fetches an initial menu from form/menu memory96 atstep102. The initial menu is prompted within a few seconds of booting the TAS firmware after the system logo. The initial menu typically presents the options of downloading a parameter stream from thedatabase server28 for enabling additional functions or printing an executive menu. If the executive menu is selected, the executive menu is retrieved from form/menu memory96. The executive menu contains numerous application options to the user, namely, selection of a form, another menu, a process, or an automatic switch to telephone mode, one of which is selected atstep104. The data streams in form/menu memory96 may be distinguished as to type (form, menu, or process) by appending a code such as “F” for form, “M” for menu, and “P” for process, and as to number by appending a form, menu, or process number at the beginning of the following data stream. These codes are recognized by the TAS firmware, and it acts accordingly.
• If the option selected atstep104 is a form, the proper form (data stream for form F_xy) is fetched from form/menu memory96 atstep106, atransaction buffer97 equal in length to the size of the record associated with the form F_xyis formed in RAM, the form is stored in thetransaction buffer97, and a connection is made to the appropriate database server(s)28. The data stream for the selected form will consist of prompts, print locations for the prompt, data entry points, print locations for the data entry start, data entry length, and a code as to the nature of the data entry. This code can be numeric, alphanumeric, a cross-reference to stored data or previously entered data, a formula for the creation internally todata transaction assembler18 of the result from previously entered data, or an external request for data, help, or reformulated values. The data stream entered into the fields of the form will not only indicate the location for the printing of the prompt and the field for data entry, but also the size of the field and the storage, a start point within the transaction buffer for the stored element, and the type of data: alphanumeric, numeric (floating point or integer), date, and the like.
• If it is determined atstep108 that the requested form is actually a menu (Mxy), a hidden set of codes pointing to the form F_xythat the selection will lead to is read, and control branches back to step104 for selection of another menu or form. When a menu is chosen, each item has its sequential number, its descriptor, and a code for what it will “call” (another menu, form, or process). In other words, each choice has associated with it a series of item codes which branch out to another form, menu, or series of tests upon the data entered. A menu also has a numeric code for each of the storage areas and a special code including a security code for certain menu items, process codes of forms within the menu, or a pointer to the process code. A pointer may also be provided in the menu for processes to be performed off-line (i.e., in an associated database server28).
• If a process (P_xy) is selected atstep104, thedatabase server28 is notified that something is requested from itsdatabase30 or that some processing of data is requested. For example, thedata transaction assembler18 may send a user “?” inquiry to thedatabase server28 so that options may be returned to thedata transaction assembler18 for presentation to the user for selection. The process triggers an external process ofdatabase server30 with a parameter stream, and control is either returned to thedata transaction assembler18 or control is held up until the process is complete, in which case a message is sent back to thedata transaction assembler18. This message can be a report, selected data, a value resulting from a calculation, and the like. Processing such as checking detectors and the like may also be performed locally bydata transaction assembler18.
• Once the desired form is selected for the user's application, the form is processed atstep110 in accordance with the steps outlined inFIGS. 8-10. As an entry is made in each field, it is automatically stored within the input buffer area of thetransaction buffer97 at its assigned location and in the dictated format. At any time, the entire form may be exited with automatic return to the menu which called it or the form can be cleared for data reentry. Once the form has been processed and transmitted to the appropriate database server(s)28, the database server connection is terminated and the user is presented atstep112 with the last menu from which the user made his or her selection. Alternatively, the executive menu will be called up as a default menu.
• If the user indicates atstep114 that he or she wishes to continue to complete a new form, control branches back to step104 for menu selection and a new database server connection is made as appropriate. This process is repeated for each form. When no further selections are desired, the TAS firmware is exited atstep116.
• FIG. 8 is a flow diagram illustrating a technique for processing a form (step110) to create a data transaction in accordance with the invention. As illustrated, the process ofFIG. 8 starts atstep118 and initializes atransaction buffer97 atstep120 for storage of the data transaction as it is being created. In other words, if there is a form for the requested application, it is moved from form/menu memory96 to thetransaction buffer97. If the requested form is not present in form/menu memory96, an error message may be sent or a request may be sent todatabase server28 for a download of a data stream containing the parameters for the requested form. Preferably,transaction buffer97 is at least as large as the largest data transaction and serves as an assembly area for the data transaction. Preferably, read and write buffers are formed so that transmit and receive buffers to/frommodem interface78 are available. Of course,transaction buffer97 may be made larger for this purpose.
• Once thetransaction buffer97 is initialized atstep120, thedisplay screen20 is cleared and the selected form is initialized to its first page atstep122. The first page is then presented to thedisplay screen20 atstep124. Atstep126, the user completes the form page on a field by field basis using any of the data entry techniques described above and the field controls ofFIGS. 9 and 10.
• Thetransaction buffer97 collects the data associated with the form presented to the user ondisplay screen20 and contains appropriate locations for each separate data element. Upon completion of the data transaction, the contents of thetransaction buffer97 are transferred to the appropriate database server(s)28 via modem or via wireless, preceded by a set of codes (field44,FIG. 2) which identify the type of data transaction and followed by a string of process identifiers for the database server(s)28 to use in its programs in creating additional transactions and in storing the data and all ancillary data transactions in the regular file format of thedatabase30 associated with the database server(s)28. As a result, the data transaction created in thetransaction buffer97 has a one-to-many relationship to the data stored in thedatabase30.
• If the user decides to abort the processing of a form at any time (step128), the form processing routine is exited atstep129. Otherwise, it is determined atstep130 whether the user wishes to go back a page (for a multi-page form) to correct a data entry. If so, control returns to step124 for presentation of the earlier page. If the user does not wish to examine or edit a previous page, it is determined atstep132 whether the current form has another page which has not been displayed for completion by the user. If the form has more pages, the routine moves to the next page atstep134, and it is determined atstep136 whether the move to the next page was successful. If so, control returns to step124 for presentation of the next page. Of course, the process of calling a subsequent page in a form or another form upon completion of a form can be dependent upon an automatic call of that page or form sequence or the ability to jump sequence (i.e., skip pages) depending upon a value in any one field that has been entered. In any event, if there are no more pages in the form or if the move to the next page was not successful, the end of the form is marked with a code and the transaction is saved atstep138 by sending the data transaction to the appropriate database server(s)28 for storage in its associateddatabase30 and “explosion” for storage of data inother databases40. If it is determined atstep140 that the save was not successful because of a modem error and the like, control returns to step122 and the process is repeated. If the data transaction was successfully saved, the form processing routine is exited atstep129 and the last menu used is presented (step112).
• Optionally, stored procedures within any data transaction form (field50,FIG. 2) are executed at the appropriate time within the flow of the form processing routine before it is exited. However, these processes may be deferred and performed by thedatabase server28 if needed.
• FIGS. 9(a) and9(b) together illustrate a flow diagram of a technique for completing and editing the fields of a form (step126 ofFIG. 8). The field completion routine starts atstep142 and first determines atstep144 whether an abort or a valid page move request is pending. If so, the field completion routine is exited atstep146. However, if no abort or page move request is pending, the field data for the first field of thetransaction buffer97 is entered atstep148. As noted above, this field data may be entered viakeyboard68 ortouch screen64, swiped in viamagnetic card interface70, read in from a memory card viamemory card interface89, read in viamodem interface78 fromdatabase server28, or designated by voice entry. Pre-edit processing of the field data is then performed atstep150. Such pre-edit processing may include, for example, setting default values, performing calculations, establishing links to data in other files, looking up and writing data to files already linked to the present form, spawning another form, performing special updates of thedisplay screen20, hiding fields from view by the user, and the like. Such pre-edit processing may also be used to determine whether modifications or actions in the present field may invalidate an entry in another interrelated field. If so, appropriate measures are taken to update all affected fields or to prevent such problems by setting appropriate default values.
• The field completion routine then checks for field errors atstep152 on the basis of the default values and the like set atstep150. If there is no field error atstep152, it is determined atstep154 whether the operator will be permitted to edit the field in the absence of a field error. If so, or if a field error was found atstep152, the operator edits the field atstep156. If the operator editing is bypassed, control proceeds directly to post-edit processing atstep158, which performs essentially the same functions aspre-edit processing step150 except that the data may be specially validated. The field is then checked yet again atstep160 for a field error. If a field error is found atstep160, control returns to step144 for processing the next field or exiting, as appropriate.
• If no field error is found atstep160, it is determined atstep162 whether the generic field validation routine of step164 (FIG. 10) is to be skipped. If so, control proceeds to step166, where the field is once again checked for a field error. However, if generic field validations are desired, control passes to the routine of step164 (FIG. 10). If no field error is found atstep166, the field is saved to thetransaction buffer97 atstep168 and the updated field value is painted on thedisplay screen20 atstep170. If the user then desires to check a previous field atstep172, control passes to a previous field atstep174 and the field completion routine is repeated for the previous field. However, if no previous field is to be checked and if it is determined atstep176 that a further field is present, control passes to the next field atstep178 and the field completion routine is repeated for the next field. This process repeats until the last field is completed and the routine exits atstep180. Control then returns toFIG. 8 for processing a different page of the form.
• Each form may be processed in one or more modes. In the input mode, described above, the data transaction is created and transmitted to thedatabase server28. However, in edit mode, upon entering the ID of a particular record, that record is read from anexternal database30 or40 intotransaction buffer97 for editing. Preferably, a record of the edits is maintained to provide an audit trail. In view mode, upon entering the ID of a particular record, that record is similarly read from anexternal database30 or40 intotransaction buffer97 but for display only. Finally, in delete mode, an entire record can be deleted from thedatabase30 or40 if the user has proper security clearance.
• FIG. 10 illustrates how the TAS firmware validates the fields of each data transaction. As shown, the field validation routine starts atstep182 and first determines atstep184 what field type is present. If the present field is an alphanumeric field, control passes to step186 where the field defaults are processed. It is then determined atstep188 whether the user knows the values allowed for this field. If not, and data is to be implanted in that field, an implant table is searched atstep190. A “?” may be used by the operator to indicated that he or she does not know the values allowed for this field and wishes to search the implant table. A list of possible values are then called up that match the data entered thus far. From this list, the operator can scroll the list and select the value that will complete the data entry. However, if the value is not found in the list, a field error is generated atstep192 and the field validation routine is exited atstep194. If the value is found in the list, control passes to step200.
• On the other hand, if atstep188 it is determined that data need not be added (implanted) into the present field, control skips to step196, where it is determined whether the present field type is a field which sets up an event in which the present field (along with its form) can be linked to any record of any file or files (one to many) of any database for the purpose of data verification and/or data extraction. If so, control passes to step198, where the data from the present field along with any other data previously gathered is used to make the desired link. As in thedata implant step188 noted above, the user may enter a “?” to get the information needed to make this link. If the data for the link is not found, a field error is issued atstep192 and the field validation routine is exited atstep194. However, if the data for the link is found, the field is checked for blanks atstep200 and a field error is issued atstep192 if blanks are present in the field but are not allowed. If no blanks are found in the present field, or if blanks are found but are allowed, the field validation routine is exited atstep202.
• If it is determined atstep184 that the present field is a numeric field, the field is checked atstep204 to determine if the character set is valid. If so, the precision of the numbers is adjusted atstep206, as necessary, and the range and scope of the numbers are checked atstep208 to make sure the field entries satisfy the boundary conditions (e.g., no dividing by zero). If the character set is not valid atstep204 or the range and scope of the numerals is not valid atstep208, a field error is issued atstep210 and the data validation routine is exited atstep212. Otherwise, the field validation routine is exited atstep214.
• If it is determined atstep184 that the present field is a date/time field, the field is checked atstep216 to determine if the character set is valid. If not, a field error is issued atstep210 and the field validation routine is exited atstep212. Otherwise, a routine of the TAS firmware checks the date/time entry atstep218 to determine if it has the correct format by performing range checking and the like. If the date/time entry does not have the correct format, a field error is issued atstep210 and the field validation routine is exited atstep212. Otherwise, it is determined atstep220 whether the present field contains a date. If not, the data validation routine is exited atstep221. If so, the date is checked atstep222 so see if it contains a weekend, and, if so, checks atstep224 whether a weekend date is an acceptable reply for this field. It is then determined atstep226 whether the calendar file is to be checked, and if so, the calendar file is checked atstep228 to see if the date is valid (e.g., not a February 30 and the like). Finally, it is determined atstep230 whether a warning date has been exceeded, and if so, a field error is issued atstep210 before the field validation routine is exited atstep212. Otherwise, the field validation routine is exited atstep221.
• Those skilled in the art will appreciate that, in order to maintain security, the TAS firmware may also present a security form for password entry to the user. The security form and ID of thetransaction entry device12 is then encrypted and transmitted to thedatabase server28 associated with the particulardata transaction assembler18.Transaction controller36 of thatdatabase server28 will then act as the transaction controller for thatdata transaction assembler18 and will check passwords and the like during operation to make certain that data security is not breached.Database servers28 may disable adata transaction assembler18 if unauthorized use is attempted. In this manner, only the appropriate person may view each menu. Of course, a different number of security levels and different executive menus may be presented as desired, all under control of thetransaction controller36.
C. Database Server28
• As noted above, thedatabase server28 acts as a vehicle for separating data transactions created by thedata transaction assembler18 into the component parts thereof which may be stored directly in one ormore databases30 and40. In other words, thedatabase server28 explodes the initial data transaction into data transactions for many different files for updating records in the files, and the like. Also, thedatabase server28 may be virtual as well as real, exist in a single machine or in multiple machines, in whole or in part.
• Generally, thedatabase server28 handles any and all data transactions received, manipulates data in the data transactions, spawns or starts processes or reports requested by a data transaction, and explodes the received data transactions into all sorts of data transactions that were spawned by the initial data transaction.Database server28 can also update values in existing records and can switch to a process for processing values in the records as necessary. In this manner, a single data transaction can define actions causing multiple files to be updated.Database server30 also handles requests from thedata transaction assembler18 and processes them as needed. Such requests may include data I/O requests, data locking and unlocking, report processes, and requests for new forms or menus. Those skilled in the art will appreciate thatdatabase server28 maintains the one-to-many relationships that exist between the user and the system of the invention, the one-to-many presentations to the user and files in thedatabases30 and40, and the one-to-many data transactions and the ancillary records, updates, and postings as may be required to diverse computer files ofnumerous databases40, thetransaction entry device12 and thedatabase servers28.
• As noted above,transaction buffer97 collects the transaction data associated with the form presented to the user viadisplay screen20. Thetransaction buffer97 is the image of the data transaction with appropriate locations for each separate data element. The contents of thetransaction buffer97 are transferred to thedatabase server28 viamodem interface78 or viaRF transceiver90, preceded by a set of codes44 (FIG. 2) which identify the type of transaction followed by a string of process identifiers for thedatabase server28 to use in its programs, in creating additional data transactions, and in storing the data and all ancillary transactions within thedatabase30 in the regular file format of thedatabase30. In other words, thedatabase server28 determines what type of action to take based on the type of data transaction received, “explodes” a data transaction into a plurality of other data transactions for transmission to other databases, as appropriate, and converts the data for its associateddatabase30 into the proper file format. Of course, eachdatabase server28 is different from eachother database server28 since it will handle different types of data transactions, have different operating system characteristics, and different file conversions to make in accordance with the file formats of its associateddatabase30. For example, thedatabase server28 may operate under an operating system such as Unix, Windows, or DOS, where the operating system provides thedatabase server28 with links to the hardware functions normally handled by an operating system. Preferably, thedatabase server28 also operates with menus, forms, and the like in the same fashion as thedata transaction assembler18 except that it stores the data transactions in its associateddatabase30 as transaction files.
• As just noted, the purpose of thedatabase server28 is to process the data transaction from thedata transaction assembler18 and to either explode the data transaction into all of its related components for storage, to handle the storage of items from the explosion process, to store the data transaction itself for reference purposes, and to act as a supplier of information to thedata transaction assembler18 in response to requests during the creation of the data transaction and during the downloading of parameters for menus and forms to thedata transaction assembler18. If desired, thedatabase server28 can also supply information back to thedata transaction assembler18 after a data transaction is received or can initiate a process leading to the delivery of a report, data, or menu to thedata transaction assembler18. In addition, thedatabase server28 anddata transaction assembler18 can reside on the same machine so long as the database server's operating system recognizes the TAS firmware or the TAS firmware is modified for use with the operating system of thedatabase server28.
D. Applications of the Invention
• As outlined above, the present invention includes a point of transaction device which presents a menu to a user from which an option is selected. A form tailored to the selected option appears for guiding the user through data entry. The full details of the data transaction are captured as data is entered by the user. Modem interaction with a central database(s) or a user database(s) allows for interaction for help and verification of certain entered data. The completed transaction is then transmitted to the central or user database for further processing and storage. Data input can also be provided via a swipe card or smart card, from data received from any database accessible via the modem interface, or other known methods.
• A data transaction system of this type may be used for many applications. For example, in a first, presently preferred, application, thetransaction entry device12 is located in a medical office for entry of patient data. In this application, a swipe card identifies the patient, a smart card identifies the doctor, and the modem connection allows the entire claim transaction to be entered and transmitted to the insurance companies for processing. The patient records may also be automatically updated and prescriptions created, given to the patient, transmitted to the pharmacist, and transmitted to the payor and patient record. Patient instructions such as special diets, exercises, treatments, appointments, and the like may be printed from the data transaction form at the doctor's central computer. In addition, a video image or picture provided viavideo input74 and compressed bydata compression circuitry75 permits an image of a medical condition such as a rash to be appended to the data transaction (inmiscellaneous processing field50 ofFIG. 2) for transmission with the patient's name, the date, a description of patient symptoms, and the like. Similarly, a recorded heartbeat may be appended to the end of the data transaction for transmission with the patient data.
• The data transaction entry system of the invention also has numerous home uses. In a preferred home use, the transaction entry device is used for performing bank transactions from the home. In this case, forms would be made available by the bank for different types of bank transactions. These forms would then be downloaded to the transaction entry device in the customer's home and used in creating and transmitting data transactions to the bank computer for off-line processing.
• As another example, the user may dial-up to a 900 number to get an interface to a central database which will download codes intoTAS PROM95 or form/menu memory96 which enable the generation of infrared signals at certain frequencies. The user needs only to specify the type, make and model of any electronic device to be controlled in order to get the desired code. Then, to operate any electronic device in the home, the user would be directed by menu prompts. Thetransaction entry device12 would then emit an infrared signal via infrared transceiver(s)80 to operate the electronic device, initiate a call via modern for a broadcast program, or initiate timed requests for video recording, turning the video recorder on and off, and the like.
• For other home uses, thetransaction entry device12 may also initiate, via menu prompts, sequences for turning on and off various household devices including alarm systems, coffeemakers, and the like. In this mode, thetransaction entry device12 may receive an RF or infrared signal indicating that a burglar or fire alarm has been activated and call up a form for calling the police or fire department, as appropriate. A call to thetransaction entry device12 may then be used to turn off the burglar or fire alarm by changing a field in a form which instructs theinfrared transceiver80 orRF transceiver90 to send an appropriate control signal to the alarm device. This feature may also be prompted from a car phone via remote initiation of the form performing this function.
• Thetransaction entry device12 may also control all household telephone use as well as controlling the answering machine and keeping a telephone transaction log. The user may also pay household bills by completing an appropriate form and transmitting the form to a payee such as a credit card company, a bank, and the like. In short, the transaction entry device will permit the owner to connect to a remote database without owning a conventional computer system with an operating system and the like.
• For personal applications, thetransaction entry device12 may be used to initiate a facsimile transmission, to provide telephone lists with automatic dialing upon selection, to provide expense accounts, personal scheduling, tax record keeping, and the like, and to provide direct access to travel information. For example, thedatabase server28 may be an airline reservations system. In this application, thedata transaction assembler18 dials the modem of the airline reservations system when the user requests data entry into an airline reservations form available at the user'stransaction entry device12. Thedata transaction device18 modems thedatabase server28, and the operating system of thedatabase server28 selects interface programs for the airline reservations system. The interface programs call thedatabase servers38 of the airlines, retrieve the appropriate menu fromdatabase40, and modem the menu to thedata transaction assembler18. Thedata transaction assembler18 then displays the airline reservations menu on itsdisplay screen20 for completion and transmission back to the airline reservations database server for processing. The swipe card may be used to provide credit card payment information and may be updated by permitting thedata transaction assembler18 to write to the swipe card. The user may also access frequent flyer club and mileage data, special offers on hotels, cruises and other travel, and the like.
• In another home (or business) use, thetransaction entry device12 may be used to eliminate conventional phone mail greetings by enabling the caller'stransaction entry device12 to read in a set of visible menus from the called party's voice mail menu so that the calling party may select the desired options using a visible menu rather than a voiced menu. In other words, the caller would not have to wait through the litany of voiced phone mail options before making a selection and could make the desired selection right off of his or her own display. This would be accomplished by selecting a process from the menu of thetransaction entry device12 which will create a “visible” menu. When such a process is selected, thetelephone electronics14 ormodem interface78 makes a telephone connection to a remote phone mail system. Once the connection is made, thedata transaction assembler18 sends a data request for a visual representation of the phone mail menu of the remote phone mail system via the telephone connection to the remote phone mail system. A data stream containing the visual representation of the phone mail menu from the remote phone mail system is then returned via the telephone connection and stored in form/menu memory96 and presented to displayscreen20 of thetransaction entry device12 for selection using the techniques described herein. When menu items are selected from the “visible” voice mail menu, thedata transaction assembler18 creates a data transaction indicating which menu item was selected and sends the data transaction to the remote phone mail system via the telephone connection. Based on the menu selection, the remote phone mail system then returns a data stream containing a visual representation of the next phone mail menu via the telephone connection for storage in form/menu memory96 and display ondisplay screen20. This process is repeated until the calling party is required to leave a message or the called party is reached. Such a system would be particularly helpful for interacting with voice mail systems, such as those at government offices, where numerous options are presented for selection.
• Those skilled in the art will appreciate that the invention is unique by virtue of its ability to generalize applications to forms so that no code need to be written to implement a particular function. However, if code is needed or if multimedia data is to be part of a data transaction, it can be attached to a form which is stored as a parameter stream in a stream of data. Also, though thetransaction entry device12 has been described as a computer workstation, it can also be used in conjunction with an optional off-line storage device as a self-contained workstation and database unit independent of traditional operating systems. Thetransaction entry device12 can also be used with an additional optional plug in as a network server or as a user interface in a network docking station.
• Those skilled in the art will also appreciate that the foregoing has set forth the presently preferred embodiments of the invention but that numerous alternative embodiments are possible without departing from the novel teachings and advantages of the invention. Accordingly, all such modifications are intended to be included within the scope of the appended claims.
