Flexible Service-oriented Integration Of Data With Rapid Release Model

With the rapid development of enterprise and the improvement of the level ofinformation technology, it needs a generic integration tool for the integration ofheterogeneous data.And it provides a global transparent access. Middleware-based dataintegration methods, it use flexible software development theory for data integration andpublishing, this article will focus on the key of technologies and issues in-depth study ofthe data source description and integration mapping.Firstly, middleware-based data integration methods and use the theory of flexiblesoftware development. A flexible service-oriented integration of data model ispresented.Which includes access control layer collaboration layer and data layer. Accesscontrol layer could connect various data sources.Data source and integrated mapping canbe described on the flexible control platform.It use message mechanism for messagepassing. In collaborative layer, the message was send over to perform data synchronizationand update the description.Message detector could verify the message and handleerror.Synchronization detector detect the data synchronization in real-time. Collaborativefeedback device can process error message and no synchronous data to ensure that alllayers could work together.The data layer is used to store the integrated data, the datasource description, the integrated mapping information and heterogeneous data typeinformation.The model is published in the form of web service.It could be used alone orbe the secondly developed for other system.Secondly, a data access layer and service layer of rapid data dissemination model ispresented based on service-oriented. The data access layer is used to connect to the datasource and configurate integrated data. The service layer is used to the integrated databasedata in the form of WebService.It is used for clients with legal verification call.Finally, in order to validate the feasibility and effectiveness of the model, it designsand develops flexible heterogeneous data integration and publishing platform.It used theintegrated platform for Yanshan University’s financial query system and combined withthe integrated analysis and published results to verify the theory.
