Study On Application Of Enterprise Information Integration Technology Based On SOA

Currently, most enterprises are facing the problems of information isolated islands; each application system can not cooperate with others. On the other hand, business information and data resource could not be instantly exchanged among enterprises. The key to solve these problems is to integrate all the heterogeneous data sources of enterprise application systems and offer a uniform interface to access these resources. Moreover, it is necessary to design and establish an effective data exchange method to help enterprises share their information.In view of the above questions,with the goal of solving enterprise data integration, starting from the point of view of reuse and the business logic reuse and flexibility in scheduling,restructuring, the establishment of a higher degree of multiplexing, business processes can be flexibly programmed basic framework of the platform, and combining some new thought and technique currently, put forward a kind of framework of enterprise information integration based on SOA. With loose coupling, simple, exoteric characteristics, it solves problems such as bad expansibility, high complexity and bad compatibility, which exist in traditional Enterprise Information Integration. As a result of the importance of enterprises information and the great researching foreground of SOA technology, there is definite signification of theory and realism in the work of the paper.Firstly, the paper introduces the background of enterprise information integration, the key technology XML, Web Services, SOA and Workflow that involved in information integration process and analysis the relationship of SOA, Workflow technology and Enterprise Information Integration. Then for the characteristics of Minor Enterprise, a Minor Enterprise Oriented Information Integration Platform was designed. In order to implementation MEIIP effectively, presents a SOA-based Enterprise Information Integration Framework, analysis the application of the framework and giving the key components of a framework, such as the design and implementation of SOAP integration engine, service call, workflow, business logic classes. Combine with specific examples, the development of specific services and the call flow process was given.
