Soa-based Power Enterprise Information Integration Realization

With the development of IT technology, Power Enterprise Information Systems are increasingly large, between the various subsystems are becoming more complex, Infomatian shown great heterogeneity and redundancy, the demand for information integration is getting higher and higher, Service-Oriented Architecture (SOA) applications can be very timely to address these issues, SOA is on a higher level of abstraction than the Component-Oriented and realizing loosely coupled information, in line with the requirements of information integration. So reserching of the power enterprise information integration based on SOA is becoming necessary and meaningful.This paper first introduces the status of the power enterprise information systems, SOA relevant theories and methods, Web Servieces followed for the implementation of the SOA approach are described, and expounds the contact with distinction on SOA and Web Services; and then based on information integration related to the theory comes up with the implementation of the power enterprise information integration program, finally, under the actual situation of the power enterprise information systems, using the technologies related Web Services, develops of the information integration system based on SOA. Virtual information integration methods have been applied to the devolepment of the system, optimizing the data storage and management, reducing the cost of data management, and improving the System operating efficiency through information integration and the combined package of services .
