Design And Implementation Of Enterprise Application Integration Based On SOA

Along with the popularization of e-Commerce and the development of the business of the corporations, requirements of collaboration among supply systems of inter-corporations and inner-corporations become more and more popular. And traditional integration technologies of enterprise applications cannot adapt to the quick increment of the enterprise information system. The birth and development of SOA (Service-Oriented Architecture) provides a new integration technology for enterprise applications. Implementation enterprise applications integration with SOA architecture and technology can avoid shortcomings of old technologies. It is now become a very important topic to research and apply the integration of enterprise applications based on SOA architecture.This paper involves deep research and analysis of the theory of enterprise application integration based on SOA architecture, and implementation of integrations between online sale system of one steel corporation and the franchisee stock system, integrations between desktop sale systems of the steel corporation. The mainly tasks of the paper are following:1. Analysis and research the theory of EAI, the model of EAI based on SOA, the mechanism and security theory of Web service, the implementation and mechanism of JAXM (Java API for XML Messaging), JAX-RPC (Java API for XML RPC) and JAXR(Java API for XML Registries).2. Through analyzing the disadvantage of old flow of purchase and the endpoint of sales which is based on database of desktop, Combining the model of EAI, which based on SOA, I designed the Web services into left services and merge services according to the service functions of the sale integration system.3. In J2EE platform and the running environments, combining with the mechanism and implementation of Web service, JAXM, JAX-RPC and JAXR, I designed and implemented the integration system of online sale system and desktop sale system, which are based on Web services.4. Seting up the test environments and testing the integration system.I imported the theory and model of Service Oriented Architecture into software project development of enterprise applications integration, and archived a good effect. It proves the feasibility of enterprise applications integration bases on SOA.
