Detailed description of the invention
Being described principle and the feature of the present invention below in conjunction with accompanying drawing, example is served only for explaining this
Invention, is not intended to limit the scope of the present invention.
Embodiment one, a kind of date storage method.Number the present embodiment provided below in conjunction with Fig. 1-Fig. 3
Illustrate according to storage method.
Seeing Fig. 1, the date storage method that the present embodiment provides includes: S1a, fixed at DDL ccf layer
Table rule is divided in a justice point storehouse.
S2a, divide according to a point storehouse for definition at DDL ccf layer that table is regular to carry out a point storehouse by source data and divide table,
Form multiple sub-block, and each sub-block is stored to corresponding MDL.
The sub-block of self is synchronized to the multiple from data base of correspondence by S3a, each MDL;
Wherein, all of MDL as writing data base, all of from data base as read from database.
Concrete, when there being mass data to need storage, application program is at DDL (Distributed Data
Layer, distributed data layer) point storehouses of ccf layer definition data divides table rule, concrete mainly defines
The data division rule of source data and each the sub-block correspondence formed after source data being divided are deposited
The type of database of storage, such as, which sub-block is stored in oracle database, which subnumber
According to block depositor in Mysql data base.
At DDL ccf layer, according to the division rule of definition, source data is divided into multiple sub-block,
And multiple sub-blocks are deposited by the type of database of each the sub-block correspondence storage according to definition
Store up to the MDL of corresponding types data base.Wherein, can be found in the Web of Fig. 2, J2EE application layer
Source data is sent to service layer by layer, and source data is sent to again the distributed number of DDL ccf layer by service layer
According to layer (Distributed Data Layer), a point storehouse for distributed data layer definition source data divides table to advise
Then, each sub-block after dividing table by point storehouse stores to corresponding MDL, each main number
Multiple from data base to having according to storehouse, each MDL will be stored in the sub-block of self and synchronizes to deposit
Store up to corresponding multiple from data base of this MDL, i.e. each data from data base and main number
According to the data consistent in storehouse.See Fig. 3, J2EE layer and source data is sent to DDL ccf layer, at DDL
Point storehouse of ccf layer definition source data divides table regular and that each MDL is corresponding is multiple from data
The data query routing rule in storehouse, divides table rule that source data is divided into multiple sub-block according to a point storehouse,
Being stored by each sub-block to corresponding MDL, all of MDL is as writing data
Storehouse, all correspondences from data base as read from database, therefore, by the data syn-chronization in MDL extremely
After data base, all of attribute from data base is set to read-only (read-only) attribute.
Such as, now need to be stored in data base the ID card information of each provinces and cities, can be according to identity card institute
Belong to provinces and cities to divide, and the ID card information of each provinces and cities after dividing stores the master to corresponding types
In data base, such as, the ID card information of Beijing area is stored in the MDL of Orale data,
The ID card information of District of Shanghai is stored in the MDL of Mysql data base.Each MDL
Corresponding multiple from data base, by the data syn-chronization in each MDL to corresponding multiple from data base
In, MDL as writing data base, multiple from data base as read from database.
It addition, data point storehouse divides table rule can dynamically adjust change, the present embodiment can use note
The mode dynamic of ShardingRule changes a point storehouse and divides table rule.
Embodiment two, a kind of method for reading data.The data provided the present embodiment below in conjunction with Fig. 4 are read
Access method is described.
Seeing Fig. 4, the method for reading data that the present embodiment provides includes: S1b, fixed at DDL ccf layer
Multiple data query routing rules from data base that each MDL of justice is corresponding.
S2b, when receiving data read request, according in data read request request data identify,
Search corresponding MDL.
S3b, according to multiple data query routing rules from data base corresponding to this MDL, from from
Data base searches the data corresponding with data read request.
Concrete, large batch of data point storehouse is divided table to store to corresponding data base by above-described embodiment one
After, application program can be corresponding multiple from data base's of MDL each defined in DDL framework
Data query routing rule, i.e. under same MDL, inquires about each order from data base,
It is specifically as follows poll inquiry, it is also possible to for each, priority, first Query priority are set from data base
High from data base, then Query priority low from data base.
When receiving data read request, first identify according to the request data in data read request,
Search corresponding MDL, such as, when in data read request, the ID card information in Shanghai is read in request,
First search the MDL of correspondence storage Shanghai ID card information, then corresponding many according to this MDL
The individual data query routing rule from data base, from corresponding the searching and number of this MDL from data base
According to the data that read requests is corresponding.
Embodiment three, a kind of data-storage system.The data provided the present embodiment below in conjunction with Fig. 5 are deposited
