The heterogeneous system data synchronization extension service can configure different data processing modes to synchronize data according to the data requirements of different systems by using the design idea of the microkernel.
The standard intermediate library service has the advantages that the two parties mutually define the intermediate library, the data are placed into the intermediate library by the issuing party, and the data can be fetched from the intermediate library by the receiving party, so that the isolation among the databases is realized.
The first embodiment is as follows:
the service body management part abstracts the data receiver into a concrete data, can describe the data receiver and control the service and the service validity period.
To implement this mechanism, a service owner table is built, recording a description of this data recipient.
The service owner table structure is specified as follows:
the data version service part manages each data release as one version, and can access the data to be released each time through the version.
In order to realize the mechanism, a release version table and a release data version table are established, the release version table represents the description of the release at this time, the release data version table records the data to be released at this time, the two tables are related tables, and one release version may compare with a plurality of pieces of release data.
The release version table structure specification is as follows:
the published data version table structure specification is as follows:
before data is released each time, the associated data management service acquires other associated data through core data to be released (namely, data stored in the version standard) and releases the data as a whole instead of a table or an entity class.
Each data release type has logic realization of obtaining associated data, management data obtaining modes for obtaining each data release are configured, main data are taken out from a release data version information table in a corresponding mode, other associated data are automatically obtained by the main data, and after organization and processing are carried out, the data released at this time are organized into a complete data packet for a data receiver to use, so that the integrity and the affairs of the released data are realized, and a micro logic processing core based on business and service is formed. The structure of the expansion configuration is as follows:
<GetDataConfig>
<add id="LBMMATERIALS" name="LBMMATERIALS" dllname="Com.MasterData.Publish.dll" implclass="Com.MasterData.Publish.Action.GetPublishMatData" />
<add id="LBMVMAPPINFOS" name="LBMVMAPPINFOS" dllname="Com.EnterpriseManage.Publish.dll" implclass="Com.EnterpriseManage.Publish.Action.GetPublishEnterpriseData" />
<add id="LBMVMCHARGESTANDARD" name="LBMVMCHARGESTANDARD" dllname="Com.EnterpriseManage.Publish.dll" implclass="Com.EnterpriseManage.Publish.Action.GetPublishChargeStandardData" />
</GetDataConfig>。
the queue scheduling service is divided into two parts, one part is to trigger a publishing mechanism automatically by a planned task, for example, data is published at a fixed time every day, and the other part is to place the data publishing as a task into different message queues to be executed respectively, namely, each type is executed in a first-in first-out sequence, but not executed immediately after receiving a message, so that the possibility of publishing concurrency problems is reduced.
In order to realize the mechanism, the service respectively realizes a planning task and a message queue by using Quartz and ActiveMQ components commonly used in the industry, and establishes the components into a windows service for management, so that the windows service controls the functions of suspension and priority improvement of the task, multi-queue scheduling and the like.
The network transmission service is to transmit data to other servers through a network, compress and encrypt the transmitted data before transmission, check the data after data reception, improve efficiency and ensure safety, perform sub-packet processing on the data, transmit big data in a plurality of small packets, and avoid the problem of packet loss easily caused by big data transmission.
The data receiving intermediate library takes a server where a data receiving system is located as a client side, and takes a data issuing system as a server side, so that a server-client side mode is formed. The data receiving intermediate library stores the issued data in the SQLite database, provides data guarantee for subsequent synchronization in a heterogeneous system, provides a daily backup mechanism, and backs up the data sent every day so as to inquire the data received every day by the client. The data required by each data receiving system can be configured in a self-defined way through the design idea of the microkernel, so that which data need to be received and backed up is determined.
The heterogeneous system data synchronization expansion service is logically realized in a user-defined mode according to the data requirements of different systems, so that the function of synchronizing data to the database is realized. The system is configured differently on different service agents to realize the operation. The configuration mode is as follows:
<SynchronizerDataConfig>
<add id="MaterialsP001" name="Materials" dllname="Com.Publish.Client.GSP001.dll" implclass="Com.Publish.Client.GSP001.SynchronizerAction.SynchronizerLBMMATERIALS" businesssystem="P001" parameter=""/>
<add id="MaterialsS001" name="Materials" dllname="Com.Publish.Client.MDMS001.dll" implclass="Com.Publish.Client.MDMS001.SynchronizerAction.SynchronizerLBMMATERIALS" businesssystem="menglong,crecgec" parameter=""/>
<add id="LBMVMAPPINFOSP001" name="LBMVMAPPINFOS" dllname="Com.Synchronizer.EnterpriseManage.P001.dll" implclass="Com.Synchronizer.EnterpriseManage.P001.SynchronizerEnterpriseManage" businesssystem="P001" parameter="OracleConnectStringP001"/>
</SynchronizerDataConfig>
the standard intermediate library service puts data to be issued into various different types of data stores in a standard data structure, so that the heterogeneous system can automatically select the database type supported by the heterogeneous system and automatically process the data from the standard intermediate library. The difference between the standard intermediate library and the data receiving intermediate library is that the data receiving intermediate library is used as a place for temporarily storing data and is an intermediate link in the publishing process, and the standard intermediate library is a target library for final publishing.
In summary, the invention provides a data publishing system between heterogeneous systems based on microkernel and asynchronous queue, so that the system has a function of publishing data according to self publishing requirements, the efficiency of publishing data can be greatly improved, the condition that a plurality of systems require different data formats for one data is supported, the data is published as a whole when the data is published, the stability and the efficiency of the updating process are improved, the asynchronous queue function ensures the efficiency of publishing data under the condition of concurrency, and the coupling between heterogeneous systems is reduced due to the existence of the intermediate library.
As will be apparent to those skilled in the art, many modifications can be made to the invention without departing from the spirit and scope thereof, and it is intended that the present invention cover all modifications and equivalents of the embodiments of the invention covered by the appended claims.
