Power Of Heterogeneous Data Sharing

To solve the problems caused by the independence, no communication, unshared information resources and non-further used data of the application systems in electric power enterprises, the data processing must be considered as the key procedure in the design and exploitation of these systems. To obtain an effective data integration in production and management of application systems, this paper proposes to construct a uniform data-switching platform.The research adopts the frame of EAI (Enterprise application integration) technology, makes use of up-to-data J2EE technological system and XML technique to construct an applicable, open, safe and uniform data-switching platform based on isomery data base. With the excellent JAVA exploitation, XML and middleware technologies, and with the management of data warehouse, the platform helps the enterprise quick establish a uniform surface for information disposal and issue, and solve the problems of information un-sharing and difficulties in integrated analysis with different platforms and systems, also the problem of absence of a uniform query and management platform. It connects the dispersive "isolated information islands" one by one, makes operators, managers and decision-makers handle all kinds of information resources according to their different authorities openly, easily and safely. At the same time, it fully utilizes the impetus and contributions of information to enterprise business, makes them satisfy the actual requirement of data sharing, and then improves the information utilization in the enterprise. This has become the guidance for information constructions.The paper is the application and realization of the data integration of EAI to electric power enterprises. In the paper, the normalized definition of the data interface is discussed and the software of "the switching system of isomery data" is exploited, which can make the data in different application systems and isomery databases be shared, so to solve the communication and sharing problems between different data layers. Through the testing and try-on of this platform in underling factories, good performance of inter-operation and information sharing between DB2, Oracle, SQL Server, Foxpro and Access is obtained. Independent exploitation of the data-switching system can greatly decrease the expenses of the application information software. Also, the application of the data-switching system can largely reduce the running cost and improve the management of the enterprise.
