Second embodiment
Referring to fig. 2, a second embodiment provides an embodiment of an Enterprise Service Bus (ESB) based shared data center. The shared data center comprises a Web service layer, an enterprise service bus, a service layer, a display layer, a logic layer, a persistence layer and a shared database;
the Web service layer provides access data service for other application systems, and comprises some operations for data synchronization of the shared data center; the presentation layer completes management of the shared data center, which includes functions of metadata management, system daily maintenance and the like.
The shared database comprises two parts of data, a stub of interactive data and metadata of a shared data center. The interactive data stub is mainly used for ensuring the accuracy and uniqueness of data among various systems, the data defines and manages a shared data center model, the normal operation of the shared data center is ensured, and the shared data center does not provide functions of inquiring and modifying the data and the like due to the consideration of safety, so that the problems of various systems caused by abnormal data are avoided.
Referring to fig. 3, the main function of the shared data center is to implement data sharing, i.e. synchronization and exchange of data. The shared data center copies the data of the application systems to the data exchange area, and stores the data in the exchange area after cleaning and converting the data in the theme library, and then distributes the data to each application system. The shared data center is divided into two main parts: a data exchange area and a theme library.
A data exchange area
The shared data center creates a database user for each application system, the resource owned by the user is called a data exchange area, and the following types of objects exist under the user:
(1) the method comprises the steps of creating a materialized view which is a local copy of remote data in a data exchange area according to a table which needs to be imported by an application system database, and refreshing the views in an ESB bus at regular time according to needs, for example, starting a regular refreshing task in a QuartZ (task scheduling framework, which is specially used for scheduling concurrent tasks).
(2) The materialized view log can be established to uniquely identify one physical address (ROWID) or primary key (PRIMARY KEY) type according to the requirements of quick refresh of different materialized views, and can also select whether to include a list of specified columns and the like.
(3) Before data cleaning, the increment table queries data which change from the last cleaning to the current time according to the materialized view log, and then stores the data into the increment table to wait for cleaning.
(4) And when the data of the application system is cleaned, the data is stored in the theme base, corresponding records are also distributed to the data to be transmitted corresponding to other application systems, and the data of the tables are transmitted to the corresponding application systems by the transmission task.
Second, theme library
The subject library is a core area of the shared data center, and stores data after the application system is cleaned, wherein the cleaning in the embodiment of the invention can also be understood as conversion, namely, the conversion of the data from a business model to an analysis model is realized by a library function, a custom script and the like aiming at a model established by a data warehouse, and the obtained final result is data which is provided externally and accords with the specification, namely the final shared data center data.
With continued reference to fig. 2 and 3, a series of data import (or data replication), flush, and dispatch actions of the shared data center are scheduled through the ESB bus, and include four main steps:
the method comprises the steps of firstly, copying application system data, and importing data (namely increment data) which is newly added or changed by the application system into a corresponding increment table of a shared data center data exchange area, wherein the step can be finished by calling a shared data center Web-Service through the application system, and can also be obtained from a materialized view by starting a timing task through QuartZ of the shared data center.
Step two, data cleaning, which is a process of transferring temporary data storage to a subject library, and at this stage, the storage process is called by a Unified Message Object (UMO) of the ESB to realize the data cleaning and storing process, so that the module mainly generates a data cleaning and storing process of transferring temporary data storage to central data storage.
Specifically, there are two ways to start a data cleaning task, one is to configure the cleaning task as OutBound, after data is imported by WebService or QuarZ task, the ESB bus immediately triggers the corresponding data packet to go out to the management module (OutBound) for data cleaning, in this process, the data cleaning task is executed passively (a passive trigger scenario, a WebService service is called by another application system to upload a request content and a request data format, and then a shared data center cleans or converts a response content into a required data format), and this way is generally adopted for data with higher real-time requirements; in another method, a data cleansing task is configured in QuartZ, and the QuartZ task is periodically started as a packet to a management module (InBound).
And thirdly, distributing the cleaned data from the theme base to a data exchange area (the theme base is a database, and the cleaned data needs to be taken out to the data exchange area), on one hand, updating the cleaned data to the theme base of the shared data center, and distributing the cleaned data to data tables to be transmitted of each application system needing the data, and deleting the increment tables of the corresponding systems after the distribution is finished.
And fourthly, transmitting the data in the data exchange area to an application system, and updating the data to be transmitted in the data exchange area of the shared data center to a database of the application system.
Referring to fig. 4, the structure of the shared data center of the present invention is divided into three layers, which are a data layer, a service layer and an application layer, and the functions are as follows:
(1) and the data layer is the bottom layer of the system and is responsible for describing and packaging the data into service according to the behavior of the data provided by the shared data center, then registering the service into the service registration center, and when the service is called, executing the corresponding behavior by the database and returning the result to the previous layer.
The enterprise service bus is used for packaging behavior description of data provided by a data source into a service; when the service is called by the system, the service is responsible for activating corresponding behaviors in the data source and returning the result. The service registry is used for registering the service according to the service description submitted by the data center.
(2) And the service layer is responsible for receiving the query request from the previous layer, calling the corresponding service according to the existing service registration information and transmitting the service to the previous layer.
The SOAP router is responsible for mapping requests with services of the data center. If the corresponding service exists, sending a request message for calling; if there is no corresponding message, the application is to be declared that the request cannot be executed. When the request message is sent, the SOAP router accepts the results returned by the enterprise service bus and passes them to the application.
(3) And the application layer is the topmost layer and provides an access interface for an external application system.
Referring to fig. 5, the basic steps of the application system or user accessing the shared data center are as follows:
the application program makes a request according to the requirement;
the request is matched with the service registered in the service registration center, and the result is recorded;
the SOAP router sends a service calling request to the shared data center according to the calling of the request, and the SOAP router is used for transmitting SOAP messages;
the enterprise service bus receives the service request, activates the service, acquires the executed result and returns the result to the SOAP router;
and the SOAP router packages the received call result into a SOAP message and transmits the SOAP message to the application program.
In the embodiment of the invention, the ESB-based shared data center meets the requirements of real-time performance of data transmission and low coupling performance and expandability between the shared data center and each application system, arranges the data of the existing system, gradually removes dirty data existing in each information isolated island, and ensures the authority of the data in the shared data center; data docking with the existing application systems is completed through the shared data center, and correctness of core data interaction between the systems is guaranteed; according to business requirements, data support services are provided for future application systems, namely, newly added systems can realize data synchronization with the existing system only through services provided by a data center.
