Research On Integrated Framework Of Enterprise Information System Based On SOA

With the development of the science and technology, enterprises have developed allkinds of application systems according to their business needs. While due to historical reasons,these application systems just considered enterprises’ local requirements, resulting in the lackof overall planning of the whole enterprises’ informatization. Because there was no uniformtechnical and data standards for most application systems, and the lack of necessaryco-construction and sharing, thus, one after another "information isolated islands" appeared.The phenomenon of information isolated islands, to some extent, hindered the effectivemanagement of enterprises. Its negative effect was obvious. With the rapid development ofinformation technology industry, information needs to be exchanged between all these kindsof enterprises’ business system, so the demand to set up the integrated informationmanagement is urgently. The effective solution is: the establishment of a comprehensiveService Oriented Architecture (SOA) can better integrate the enterprises’ internal and externalresources. System integration can not only integrate the different systems within enterprises,but also integrate the different systems of different companies outside the enterprises.Through the integration platform, the problem of “data isolated island","information isolatedisland","application isolated island" can be solved.The main research work of this paper: put forward the technology selection and thedesign method of ESB service integration platform and data exchange mode based on SOA,in the premise of serious analysis of relevant technologies and standards, such as EAI、ESB、SOA, etc. This paper applies the establishment of a comprehensive service orientedarchitecture (SOA) to the integrated information management. Through the analysis ofservice-oriented integration technology, and the deep analysis of the design case of integratedplatform of the department of land and resources, this paper, combined with the actualsituation of the current information application of the industry, it puts forward a plan onestablishing the enterprise information system application integration on the basis of the oldsystems. This paper introduces the definition, the level and the development process ofEnterprise Application Integration (EAI), and makes an analysis of the service-orientedintegrated technology. It gives the functional requirements of XXX Bureau’s electronicmonitoring system, and describes the design of the whole frame of XXX Bureau’sinformatization system and the software system structure of integrated system. It also putsforward the realization detail of ESB service integration platform and data exchange modewhich is based on SOA, and it designs the main data integration, the service integration, theprocess integration and the integrated solutions with various platforms.Finally，this paper is based on the background of the electronic monitoring systemproject of XXX Bureau. Combined with Web service-based and the application integrationtechnology of SOA architecture, it makes a simple implementation of the core technology ofapplication integration, verifying the efficiency, the convenience and the superiority of packaged-integration through SOA architecture by using Web.
