For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawings and specifically real
The present invention is described in further detail to execute example.
As in figure 2 it is shown, one embodiment of the invention provides updates the method sharing data, the method can
To comprise the following steps:
Step 201: the link information of each database is set, and determines unified JDBC interface mode.
For example, existing 10 application systems, and common, each application system has one accordingly
Database.In detail, these 10 databases can be respectively database 1, database 2 ..., number
According to storehouse 10, corresponding Database Identification is respectively 001,002 ..., 010.In the present embodiment, this
10 application systems can be same enterprise, it is also possible to is belonging respectively to different enterprise.
In the present embodiment, for ease of the renewal of the data sharing of disparate databases, for these 10 data
Storehouse, it may be determined that a unified interface mode, such as JDBC interface mode.Furthermore, it is possible to safeguard one
Individual database information list, comprises specifically connect corresponding with the database of each application system in this list
Connect information.By the JDBC interface mode that this is unified, and a concrete database connected mode, just
May be coupled to associated databases.
In detail, the link information of database can include URL (the Uniform Resoure of this database
Locator, uniform resource locator), IP port, the mark of database, in account number cipher any one or
Multiple.Wherein, the data update system internal use that account number cipher can only be formed at these 10 databases.
In the present embodiment, by unified JDBC interface mode, and each data predetermined
The connected mode in storehouse, i.e. may be connected to any database, in order to realize the number between any two database
Even synchronize according to sharing, updating.This database connected mode is without setting up spy for each two database
Fixed database connected mode, thus without developing various specific connection interface, without related application system between
Joint debugging is tested, it is not necessary to the cooperation and communication between different vendor, is of value to raising interface exploitation efficiency and effect, joint
Human-saving physical resources and financial resources.Additionally, the data sharing between the database of different application systems runs with application system
Between be in loose coupling state, do not affect the normal use of application system.
Step 202: each class is set and shares the secret sharing of data, and the renewal of each secret sharing is touched
Send out conditions and data update mode.
In the present embodiment, each database can store multiclass and shared data, and each class has been shared
Data are generally held in same tables of data.Sharing data for each class, it can be to other data
Data are shared in the source that storehouse carries out sharing, it is also possible to be that data are shared in the backup shared by other databases.
For a certain class shares data, when it shares data for source, corresponding tables of data is source number
According to table, corresponding database is source database；When it shares data for backup, corresponding tables of data is
Ownership tables of data, corresponding database is ownership database.Therefore, a database both can be source number
According to storehouse, it is also possible to be ownership database.
For all kinds of shared data stored in these 10 databases, each class can be set and share data
Secret sharing.
In detail, secret sharing may include that source database mark, ownership the mark of database, SQL,
The mark of derived data table, ownership tables of data the mark SQL field corresponding with ownership tables of data in
Any one or more.Wherein, acquiescence derived data table is in source database, and ownership tables of data is in ownership
In database.And the job that secret sharing can be corresponding with such shared data describes file.
Such as, for this class of employee compensation shares data, corresponding secret sharing A may include that
Source database be designated 001, ownership database be designated 002, for obtain employee compensation SQL,
Derived data table be designated table 5, ownership tables of data be designated table 1 and ownership database in table 1 phase
Corresponding SQL field.Additionally, in a kind of possible implementation, for a class shares data,
Corresponding source database can be with more than one.
In detail, update trigger condition and may include that clocked flip-flop, and/or, monitor corresponding being total to
Enjoy data and have variation.Wherein, when updating trigger condition and being clocked flip-flop, share data automatically the most more
Newly can be completed by timer, and be configured by the statement of timer.
In the present embodiment, the different of each secret sharing can be set and trigger bar according to the actual requirements
Part.Such as, for this class of employee compensation shares data, due to the application at this shared data place
System every middle of a month, such as No. 15, can be updated the employee compensation in above-mentioned database 1.Therefore,
The renewal trigger condition of corresponding secret sharing can be clocked flip-flop, and the clocked flip time can be
Monthly 16 days 0 time whole.
Additionally, for the application scenarios needing the up-to-date shared data of timely acquisition, can select the most more
New trigger condition is for detecting that corresponding data of sharing have variation, for example, it is possible to monitoring is used for storing in real time
The renewal time of the derived data table of these shared data, change if monitoring the renewal time, can be right
Such shared data are updated.
In detail, data refresh mode includes: incremental mode, and/or, full dose mode.
In the present embodiment, can such as whether retain stale data, selectively determine according to the actual requirements
Corresponding data refresh mode.Such as, data are shared for this class of employee compensation, increment side can be selected
Formula, i.e. when carrying out sharing data renewal, retains stale data, adds newly-increased data, and only will change
Data be updated, and not all update replace.Additionally, for the shared number without retaining stale data
According to, can the most all update replacement to select full dose mode.
Additionally, in addition to considering whether to retain stale data, the selection of data refresh mode it is also conceivable to
Other factors, such as the data volume size of shared data, change degree etc..Such as, for employee compensation this
Class shares data, and owing to its data volume is less big, and data have the number of variation to account for data total amount in a short time
Ratio is relatively small, therefore can select incremental mode, i.e. when carrying out sharing data renewal, only will change
Concrete data be updated, and not all renewal.Additionally, the shared number the biggest for changing degree
According to, the most all can update to select full dose mode.
Therefore, in the present embodiment, for this class of employee compensation shares data, it may be determined that corresponding
The renewal trigger condition of secret sharing A be clocked flip-flop, and the clocked flip time can be monthly 16 days
0 time whole, data refresh mode is incremental mode.
In the present embodiment, for the secret sharing of each shared data, can according to practical application request,
Corresponding suitably renewal trigger condition and data refresh mode are set.By this shared automatically updating data side
Shared data selectively can be timed renewal or real-time update, and selectively carry out complete by formula
Amount updates or incremental update, in order to shared data are utilized by staff.
Step 203: when the time that the clocked flip-flop reached with share option A is corresponding, according to sharing
Option A, determine corresponding source database be database 1, ownership database be database 2, derived data
Table is the table 5 in database 1, and ownership tables of data is the table 1 in database 2.
When reaching the triggered time corresponding with sharing option A, the content according to comprising in secret sharing A:
Source database be designated 001, ownership database be designated 002, derived data table be designated table 5,
Belong to tables of data is designated table 1, it may be determined that corresponding source database is database 1, ownership database
Being the table 5 in database 1 for database 2, derived data table, ownership tables of data is the table 1 in database 2.
Step 204: by JDBC interface mode and the link information of database 1, be connected to database 1.
By predetermined database information list, the source database i.e. company of database 1 can be got
Connect information.By unified JDBC interface mode and this link information, database 1 can be quick connected to.
Step 205: utilize the SQL in secret sharing A, in the table 5 of database 1, obtains and shares
Data are shared in the corresponding source of SQL field in option A.
In detail, for incremental data update mode, when data are shared in acquisition source, owing to total data is same
The implementation of Shi Gengxin is relatively slow, therefore can set up inquiry vernier.By inquiry vernier, can obtain one by one
Source data, and each the source data got is processed one by one.
SQL is a kind of data base querying and programming language, and the SQL in secret sharing A is i.e. specifically used for
The language of inquiry employee compensation, SQL field is i.e. corresponding to the source data that should obtain.Therefore, arrival is being connected
After source database i.e. database 1, table 5 therein can be navigated to, and by running in secret sharing A
SQL, share data obtaining the source corresponding with the SQL field in shared option A in table 5.
Step 206: by JDBC interface mode and the link information of database 2, be connected to database 2.
After data are shared in the source of getting, same, by predetermined database information list, can
To get the ownership database i.e. link information of database 2.By unified JDBC interface mode and should
Link information, can quick connect to database 2.
Step 207: the data refresh mode determining secret sharing A is incremental mode, determines database 2
Current shared data in table 1.
In the present embodiment, the data of the corresponding secret sharing A of data are shared with this class of employee compensation more
New paragon is incremental mode, it is possible to use data are shared in the source got, by incremental mode to ownership data
The current shared data in table 1 in ownership tables of data in storehouse, i.e. database 2 are updated.
Certainly, however, it is determined that go out corresponding data refresh mode when being full dose mode, specifically, table 1 can be removed
In current shared data, then the source got shared data preserve in table 1.
Step 208: the first source of each in data is shared for source and shares data, be performed both by: judge working as
Whether front shared data existing corresponding first current shared data, if existing, performing step 209, if not
Exist, perform step 211.
In the present embodiment, when source share data be employee compensation time, the source got is shared in data
Each source data, if there is not Backup Data corresponding thereto in current shared data, then say
Employee corresponding to this source data bright is probably new employees's work, can directly perform step 211, the most directly will
This source data is added to table 1.Contrary, if there is corresponding Backup Data, then need to perform
Step 209, to judge whether this source data has change.
Step 209: judge that the whether phase of up-to-date amendment date of data and the first current shared data is shared in the first source
With, if it is not, perform step 210.
In detail, when needs carry out data renewal, can arrange according to unique index set in advance, such as member
The name of work, to carry out data renewal operation.
The most identical by the up-to-date amendment date of both contrasts, it can be determined that to go out whether the first source shares data
There is change.If both differ, data are shared in first source that illustrates change, therefore can perform step 210, with
First current shared data renewal is replaced with the first source and shares data.
In a kind of possible implementation, after data are shared in the source of getting, according to practical application request,
Can not also carry out the judgement on up-to-date amendment date, the most whether source data has change, as long as judging to return
Belong in tables of data and there is the first source to share data corresponding with the first current shared data, just currently common by first
Enjoy data to be updated to the first source and share data.
Step 210: the first current shared data are updated to the first source and share data.
Owing to both the thinnest update dates are different, illustrating compared with the first current shared data, the first source is altogether
Enjoy data and have change, therefore the first current shared data can be updated to the first source and share data.
Step 211: the first source is shared data and preserves to the table 1 of database 2.
Angelica tables of data i.e. table 1 do not comprises this first source when sharing data in the current shared data of storage,
