Specific embodiment
In being described below, in order to illustrate rather than in order to limit, it is proposed that such as tool of particular system structure, technology etcBody details, to understand thoroughly the embodiment of the present invention.However, it will be clear to one skilled in the art that there is no these specificallyThe present invention can also be realized in the other embodiments of details.In other situations, it omits to well-known system, device, electricityRoad and the detailed description of method, in case unnecessary details interferes description of the invention.
In order to illustrate technical solutions according to the invention, illustrated below by specific embodiment.
Embodiment one
Fig. 1 shows the realization stream for the tables of data backup method based on oracle database that the embodiment of the present invention one providesJourney, details are as follows：
Step S101 establishes the Backup Data table identical with the table structure of target matrix, and according to the target dataTable sets access rights for the Backup Data table.
Wherein, target matrix is the tables of data backed up, can be excel tables, for example, based on OracleThe tables of data of database.The table structure of target matrix can be excel forms table structure, comprising corresponding code information withRealize corresponding function.In addition, according to the division of function, code information that the table structure of the tables of data of different function is includedIt is not quite similar.
In addition, the table structure of target matrix can also include the information such as number and field.Specifically, each table structure canWith comprising a number, which is the unique mark of corresponding table structure；The field that each table structure is included is according to design needCan there is certain relevance.
It is described to be specially to Backup Data table setting access rights according to the target matrix in this step：KnotThe access rights of the target matrix are closed, some user, certain is set according to actual needs to the Backup Data table establishedThe access rights of user.For example, the target matrix only allows specific user to access, then can to Backup Data table intoRow setting, also only allows specific user to access, to prevent leaking data.
Step S102 obtains the type of data in the target matrix.
Wherein, the type of data can include non real-time update the data and real-time update data in the target matrix.Wherein, it is non real-time update the data refer to will not real-time update or change data, such as attendance data, performance data and all kinds of remittancesTotal data etc..Not real-time update is updated the data due to non real-time, is calculated simply by specific time, such as every nightOr monthly the end of month calculate after generate, therefore non real-time update the data only is needed that non-accountable time is selected to do and returnShelves, without the concern for the influence to business.Real-time update data refer to as operation log and certain synchronous middle table data are (sameCan update synchronous regimes fields after the completion of step) etc. can real-time update or change data.
Specifically, the type of data in identification target matrix, each data type mark can be identified by data typeKnowledge can correspond to a plurality of data.Under normal conditions, the data stored in a tables of data are a data type.
In one embodiment, the type for obtaining data in the target matrix can specifically include：
It pre-sets and non real-time updates the data corresponding with real-time update data data type mark；
Non real-time update the data or real-time update data is determined as according to data type mark in the target matrix.
Wherein, it is described according in the target matrix data type mark be determined as it is non real-time update the data or in real time moreNew data is specifically as follows：
It is identified according to the data type of every data and determines that the data update the data or real-time update data to be non real-time；Or
According to the corresponding data type mark of each tables of data, determine that the data in the tables of data are updated the data to be non real-timeOr real-time update data.
Step S103, according to the type of data in the target matrix, by the backup table tables of data by the meshData to be backed up in mark tables of data are backed up.
In this step, non real-time update the data is needed to take different processing procedures with real-time update data, with rightData to be backed up in the target matrix are backed up.
Referring to Fig. 2, when data is non real-time update the data in the target matrix, step S103 can specifically pass throughProcedure below is realized：
Step S201 goes to the data to be backed up in the target matrix in the Backup Data table.
Wherein, the data to be backed up by the target matrix, which are gone in the Backup Data table, is specially：RootAccording to time or major key, the data to be backed up in the target matrix are gone in batches in the Backup Data table.It is for example, rightThe historical data of 3 months or more does filing processing in target matrix, then can by the data in target matrix 3 months,It is inserted into batches in the Backup Data table by time or major key.
Step S202 establishes major key and index according to the target matrix for the Backup Data table.
Wherein, major key is the unique index (index) of tables of data, such as student Biao Li has student number and name, and name mayThere is duplication of name, but student number is really unique, as soon as a record is searched for from student's table as searched a people, it can only be according to student numberIt goes to search, this can just find out unique one.In another example in store complete machine and accessory in the database of some computer manufacturerProduct information, the table for preserving machine product information are called Pc tables (with reference to table), for preserve the table of accessory supply of material informationMake Parts tables (referenced table).To set external key, with reference to table (referencing table, i.e. Pc tables) and referenced tableIn (referenced table, i.e. parts tables), corresponding two fields must all set index.
In this step, after the data to be backed up in the target matrix are gone in the Backup Data table, needMajor key and index are established to the Backup Data table, so that the backup according to the major key and index in target matrixData in tables of data can normally be quoted according to the data relationship in the target matrix.
The table name of Backup Data table after establishing major key and indexing is changed to the table of the target matrix by step S203Name.
Wherein, the data to be backed up in the target matrix are gone in the Backup Data table, and according to the meshAfter mark tables of data establishes major key and index for the Backup Data table, except the table name for removing tables of data, the Backup DataTable is identical with the table structure and data information of the target matrix.At this point, after major key and index will be establishedThe table name of Backup Data table is changed to the table name of the target matrix, then can complete to back up the target matrixProcess.
By the target matrix for for attendance data table, it is assumed that be to the history number of attendance data table 3 months or moreAccording to filing processing is done, realize that process is as follows：
The Backup Data table (table name B) of one and the identical table structure of attendance data table (table name A) is created, and is examinedDiligent tables of data A carries out tax power to Backup Data table B, to realize that Backup Data table B, inquiry backup can be accessed by limiting certain certain customersData in tables of data B；
By the data in attendance data Table A in 3 months, it is inserted into batches in Backup Data table B by time or major key,Since attendance data Table A updates the data table to be non real-time, can backup be directly inserted by time or major key in batchesIn tables of data B, and without considering the problems of time order and function；
Major key, index etc. are established with reference to attendance data Table A table on Backup Data table B, so that in Backup Data table BData can be quoted correctly；
The table name of attendance data Table A is renamed as tables of data C, then the table name of Backup Data table B is renamed as Table A, you canTo complete the process backed up to the data in attendance data Table A.
Referring to Fig. 3, when data are real-time update data in the target matrix, step S103 specifically can by withLower process is realized：
Step S301 establishes major key and index according to the target matrix for the Backup Data table.
In this step, after the data to be backed up in the target matrix are gone in the Backup Data table, needMajor key and index are established to the Backup Data table, so that the backup according to the major key and index in target matrixData in tables of data can normally be quoted according to the data relationship in the target matrix.Specific explanations content can joinAccording to the related content in step S202, details are not described herein.
The table name of the target matrix is modified by step S302, and will establish major key and the backup number after indexThe table name before the target matrix change is changed to according to the table name of table.
Wherein it is possible to the operation of table name change is carried out by a new table name.For example, the table name of the target matrixFor Table A, the table name of the Backup Data table is table B, then can the table name of the target matrix be changed to table C, then willThe table name of Backup Data table is changed to Table A.
Step S303, sequence of the data in target matrix according to the record time from back to front after table name is changed,It goes in the Backup Data table after renaming.
Wherein, step S303 is specifically as follows：According to time or major key, by the data to be backed up in the target matrixIt goes in batches in the Backup Data table.For example, filing processing was done to the historical data of 3 months or more in target matrix,The data in target matrix 3 months can be then inserted by time or major key in the Backup Data table in batches.
If tables of data only has insertion operation, such as operation log, then this step does not need to interrupting service, the influence to businessWithin 1 second, almost it can be ignored.If tables of data has insertion update operation, such as certain synchronous middle table data are (synchronousSynchronous regime field can be updated after the completion), migrating data answers the new data of priority migration in step S303, and program is avoided to updateWhen report an error, to service impact about at several seconds or so, only need the processing that slightly compares to data after the completion of data filingInfluence is completely eliminated.
Optionally, it after step S303, further includes：According to data in the target matrix and the Backup Data tableIn data carry out data comparison processing, to prevent program from reporting an error when update.
By the target matrix for for operation log, it is assumed that be to the history of operation log tables of data 3 months or moreData do filing processing, realize that process is as follows：
The Backup Data table (table name B) of one and the identical table structure of operation log tables of data (table name A) is created, and is joinedIt examines operation log tables of data A and tax power is carried out to Backup Data table B, to realize that Backup Data table B can be accessed by limiting certain certain customers,Inquire the data in Backup Data table B；
Reference operation daily record data Table A table establishes major key, index etc. on Backup Data table B, so that Backup Data table BIn data can correctly be quoted；
The table name of operation log tables of data A is renamed as tables of data C, then the table name of Backup Data table B is renamed as Table A；
By the data in operation log tables of data C in 3 months, by time or major key, according to the record time after toPreceding sequence is inserted into batches in Backup Data Table A.
Further, when data are real-time update data in the target matrix, the foundation and target matrixThe identical Backup Data table of table structure be specially：It establishes identical with the table structure of target matrix according to time progress subregionBackup Data table, the Backup Data table includes the first subregion, and the corresponding initial time of first subregion is current time.For example, subregion is carried out to Backup Data table by the time, including subregion P1, subregion P2, subregion P3 etc., wherein, subregion P1 is corresponded toStart time be slightly sooner in time than current time, subregion P2, subregion P3 etc. can monthly subregion.For example, current time is May 15, thenThe corresponding start times of subregion P1 can be some day in 5 months, such as May 14.
Wherein, step S103 can specifically be realized by procedure below：
Step S401 establishes major key and index according to the target matrix for the Backup Data table.
In this step, after the data to be backed up in the target matrix are gone in the Backup Data table, needMajor key and index are established to the Backup Data table, so that the backup according to the major key and index in target matrixData in tables of data can normally be quoted according to the data relationship in the target matrix.Specific explanations content can joinAccording to the related content in step S202, details are not described herein.
The table name of the target matrix is modified by step S402, and will establish major key and the backup number after indexThe table name before the target matrix change is changed to according to the table name of table.
Wherein it is possible to the operation of table name change is carried out by a new table name.For example, the table name of the target matrixFor Table A, the table name of the Backup Data table is table B, then can the table name of the target matrix be changed to table C, then willThe table name of Backup Data table is changed to Table A.
Step S403, the target matrix after table name is changed exchange, and with first subregion after preset timeFirst subregion is removed into the Backup Data table after table name change.
Wherein it is possible to the friendship between target matrix and first subregion after realizing table name change is operated by sqlIt changes, such as sql:ALTER TABLE A EXCHANGE PATITION P1WITH TABLE C, i.e., by subregion P1 and number of targetsIt is exchanged according to the data of table C.After the preset time of data exchange is finished, the first subregion is removed into Backup Data table.
For example, the historical data to three months or more in target matrix does filing processing, and almost every in three monthsThe all possible real time modifying of a data, realizes that process is as follows：
Create the Backup Data table that subregion is carried out according to the time of one and the identical table structure of target matrix (table name A)(table name B), the subregion of Backup Data table B include subregion P1, subregion P2, subregion P3 etc., wherein, the corresponding starting points of subregion P1Time is earlier than current time；
Reference target tables of data A tables establish major key, index etc. on Backup Data table B, so that in Backup Data table BData can be quoted correctly；
The table name of target data Table A is renamed as tables of data C, then the table name of Backup Data table B is renamed as Table A；
Tables of data C is exchanged with the P1 subregions of tables of data A, detailed process sql:ALTER TABLE A EXCHANGEPATITION P1WITH TABLE C；
After data exchange is completed 3 months, subregion P1 is removed into tables of data A.
The above-mentioned tables of data backup method based on oracle database is initially set up identical with the table structure of target matrixBackup Data table, then according to the target matrix for the Backup Data table set access rights, further according to the meshThe type of data in tables of data is marked, the data to be backed up in the target matrix are backed up, does not need to the DBA people of professionMember, which carries out processing, to do data backup to case of non-partitioned tables, can greatly improve the operating efficiency of data backup.
It should be understood that the size of the serial number of each step is not meant to the priority of execution sequence, each process in above-described embodimentExecution sequence should determine that the implementation process without coping with the embodiment of the present invention forms any limit with its function and internal logicIt is fixed.
