The present invention is the method that a kind of mode by increment makes upgrading data file, it is meant that mainly a kind of data file that makes is when upgrading, the method that the data file that increases and raw data file are combined only, this method is to borrow computer system to read the raw data file of legacy version earlier, and this data file carried out initialization, and foundation filename corresponding and index with it, open the upgrade data file again, this upgrade data file is meant the content that is increased outside the original data file of legacy version, and after setting up filename corresponding with it, to initialized raw data file, combine with the upgrade data file, set up corresponding index, so, not only can reduce the archives amount (File Size) of upgrade data file, and can be for the data file of borrowing Network Transmission, shorten download time, in addition, more can provide FileVersion handoff functionality flexibly to the user by index, so that the user search upgrade before and upgrade after file, and make the user can select the operation of switching to arbitrary version at any time.

For enabling further to understand, the special Figure 1A-1B that cooperates is described as follows:

Please refer to shown in Figure 1A-1B, when legacy version upgrading that user's desire is used application program that the developer provides originally, for example: when upgrading to the S1 version by S0, wherein S0 represents legacy version, S1 then is the redaction after representative is upgraded, the raw data file that computer system can read legacy version earlier carries out initialization to this data file, and sets up index corresponding with it (0) (shown in Figure 1B).

When opening the redaction of upgrading by legacy version, wherein increased data file (δ 0.1), again this data file is transferred in regular turn by the developer and originally had among the user of legacy version, in present embodiment be see through the Internet (Internet) (only be familiar with this operator, still can disk etc. mode replace.), and data file that is increased and the data file (promptly referring to raw data file) that is stored in user's legacy version are originally combined, simultaneously, the data file (S0+ δ 0.1) of the redaction that computer system combines to legacy version and the data file that increased is set up corresponding index (1).By that analogy as can be known, when version is constantly upgraded, for example: upgrade to S2 by S1 ... during Sn-1 upgrading Sn, the developer can be constantly with legacy version (comprising that prototype version reaches than this old renewal version), when upgrading to redaction, (δ 0.1 for the data file of upgrading or increasing, δ 1.2 ... δ n-1.n), directly transfer among the user, and data file that is increased and the data file that is stored in user's legacy version are originally combined, (δ 0.1 and when raw data file and ever-increasing data file, δ 1.2 ... δ n-1.n) combines, when becoming redaction, computer system can be to these by increasing the data file that data file combines with a preceding legacy version (comprise raw data file and in ever-increasing version thereafter) respectively, set up index corresponding (0,1,2 respectively with it ... n) (shown in Figure 1B).

Moreover, please refer to shown in Figure 2ly, when the data file (this refers to prototype version) of legacy version was desired to upgrade to the data file of redaction, computer system all can read the data file that stores raw data in this legacy version earlier, and it is carried out initialization, its process comprises the following step:

At first, the filename cooperates with this data file is set, reaches unique identifier (Identify, abbreviation ID) 201 that should data file.Again this data file is divided into several data cells, and after setting a unique and corresponding identification code for each data cell, computer system can deposit the content with data cell of identification code in data file, simultaneously, the location records that this data cell is write in the data file gets off 202.Computer system can judge whether all data cells are stored and finish 203, does not finish if also store, and then returns 202, proceeds the work that stores and write down, deposits in the data file up to all data cells; If after determining all data cell storages to be finished, computer system can be provided with an index file name, in order to calling 204.

Borrow the writing position of identification code, data file identification code and the data cell of the data cell that computer system will be in data file to read in regular turn, computer system can judge whether above-mentioned all data to be read 206 fully simultaneously, if yet data are not wherein read fully, then return 205, the action of proceeding to read; If all index datas are read, then computer system can be with the index file name that sets in advance, and deposit in the description document that sets in advance by the unique identifier of Data Filename of reading in the data file and data file, this description document mainly is the related content that is used for storing relational data file and index file thereof, put the numerical value (being assumed to be 1) and the call number (being assumed to be 1) 207 of upgrading number of times, so, promptly finish the initialization of this data file, and above-mentioned data file is not limited to the data file in having used, or finish the data file of making by the developer, and be meant the data file of all desires upgradings.

Please refer to shown in Figure 3, when raw data file is finished the initialization of upgrading preceding, computer system can be opened the pairing description document of this raw data, from wherein reading the numerical value of this raw data upgrading number of times, be made as (1) from the above mentioned as can be known, and according to after (that is raw data) pairing index file name 301 before the definite upgrading this time of this numerical value (1), open again and preceding (that is raw data) the corresponding index file of this upgrading, it is noted (being assumed to be Table A) 302 in present embodiment.

Computer system can continue to open the description document of the data file of upgrading, read and write down wherein index file name and Data Filename 303, open the index file of upgrade data, after it being noted (being assumed to be table B) 304 in present embodiment, to show B and Table A through the index file upgrading processing, after obtaining the result of index upgrading, it is noted (being assumed to be table C) 305 in present embodiment, the index content that will store the record of updating result (table C) is again exported successively, this index content comprises the identification code of data cell, data file identification code and data cell writing position, so, promptly can produce an index file 306, and the index file that this upgrading is preceding sign sequence number adds 1, index file sign sequence number 307 as this upgrading, simultaneously, the upgrading secondary data of original description file is added 1 number of times as this upgrading, and increase the filename of updating result (table C) in the indexed file table, in the data file table, increase the identification code 308 of upgrade data filename and upgrade data file, so, it is exportable newly-generated description document 309, and the file 310 that all are opened in the bolt down procedure, and then reach the data purpose of upgrading.

In addition, please refer to shown in Fig. 3 A, wherein, by corresponding index file (Table A) before the index file of upgrade data (table B) and the upgrading through the index file upgrading processing, the detailed process that obtains index updating result (table C) is as follows: at first Table A is copied to 3a1 among the table C, read the first indexing units 3a2 among the table B again, computer system can judge whether these data have existed 3a3 in table C then, if exist, then with the indexing units 3a4 among the indexing units substitution table C among the table B; If there is no, promptly the unit among the table B is increased to 3a5 among the table C, then judge whether untreated indexing units 3a6 is arranged among the table B, if untreated indexing units is arranged, then return 3a3, re-execute the step of above-mentioned 3a3 to 3a6, until table all indexing units are processed among the B finish till, result is outputed to table C, the index file 3a7 after obtaining upgrading.

Moreover, please refer to shown in Figure 4, after having used the redaction data file of having upgraded as the user, when needing again to use the data file of certain legacy version, at first, open the description document in this redaction data file, read upgrading number of times and current index file sequence number (being assumed to be X) 401, the user sees through the new index file sequence number (being assumed to be Y) 402 of computer system input, computer system can be judged its index file sequence number (being X and Y) whether identical 403, that is confirm whether the index file that the user need call is current index file, if it is identical, can determine that then current index file is the index file that the user need call, need not be for further processing again, directly close this description document 406; If it is inequality, represent that then the required index file that calls of user is not current index file, then need further to confirm this sequence number Y whether effective 404, if effectively, the current index file sequence number of then putting in the description document to be write down is (Y) 405, this moment, the user was according to current index file sequence number indication, and the upgrade file of obtaining is the needed version of user, at last this description document is closed 406.

In addition, please refer to shown in Figure 5, when the user uses data in the computer system, for opening description document earlier, read the index file sequence number of the data file (that is the data file after the last upgrading) of being deposited at present, thereby determine presentindex file name 501, open present index file then, read in this index filefirst index content 502, again according to the data file identification code in this index content, and in description document, obtaincorresponding Data Filename 503, open the pairing data file of this Data Filename, according to recorded data unit writing position in the index, behind the position of specified data unit in this document, after reading thisdata cell 504, judge whether it existsnext index 505, if there is no, represent that all data cells all read in, then close all 506, make the user operate 507 arbitrarily data; If be stored in next index, then need to return 502, continue to read the content of next index entry in the index file, and carry out 503 and 504 step in regular turn, up to all index content be read finish till.
