Research On Application Integration Based On Service-Oriented Architecture

Along with the development of computer technology and enterprise information system, the application systems, established by enterprise based on many kinds of technologies and different platforms, could not effective integrated and form the information isolated island which could not share information between each other. The demand of integrating the application systems becomes more and more urgent with systems increasing. In order to reduce enterprise cost pressure and meet new demands and unceasingly changes, the enterprise must effectively reuse the existing systems to enhance the efficiency of system development. Therefore, the integration of application systems gets more and more attention.The implementation technologies of the tradition application integration have limitations in interoperability between the isomerism platforms and description of interface which causes the lack dynamically extension of the integrated system and insufficiency of the isomerism platform interoperation. To solve this problem, this paper applies Service Oriented Architecture (SOA) to application system integration which provides one kind of dynamic and expandable architecture to enterprise application integration. Moreover, Web Services is gradually mature to provide technical support to SOA and enterprise application integration.Firstly this paper analysis and studies present research achievements of domestic and overseas, and then studies the related technology and concept of SOA and Web Services. After discussed the related theory, this paper proposes a service-oriented application integration architecture based on Web Services and studies its software level, then design the implementation flow of the integration. Then with the background of the integrated project of Qinhuangdao group and the theory of proposed service-oriented architecture based on Web Services, this paper analysis and designs the application system integration of Qinhangdao group, and conducts the key research to the Web services combination. Finally this paper implements the integration system's server end and customer end, and discusses the Web services security. The service-oriented architecture of application integration based on Web Services proposed by this paper applied in the actual project, and completed the integration of crossing platforms, systems, and languages to overcome the insufficiency of the tradition application system integration technology. At the same time, the application system integration architecture proposed this paper, may widely use in other information system integration.
