Research Of Implementation Application System Integration With SOA Based Web Service

Internet is a distributed heterogeneous information platform. There are various application systems on Web, from simple WWW browse to complex electronic commerce, electronic government, etc, There are large differences about the development language,deployment platform, communication protocol, format of the exchanged data among these Web applications. How to integrated these different system has become a problem that must been solved urgently. Traditional distributed techniques such as CORBA, COM+, EJB etc, are depended on specifically platforms, therefore information share is difficult to realize between different Web applications. But they have to connect and transfer data to each other,even through the Internet.So a new technology is necessary to resolve these problems.And the business process always changes as the high development of business.Thus,the flexible system integration with strong maintainability and expansibility is on the top of needs.Service-oriented architecture can well resolve the problem of system integration.The technology of web service is becoming riper in recent years and the standards on it are relatively perfected.These are the technological foundation and guarantee for the service-oriented architecture (SOA).In this paper,we will discuss something about the appliction integration of the Web services based on a large-scale distributed system,and the means of XiaMen Urban Construction Secondary Vocational School implementing information system integration.Future more,we will consider the project of building XMUCSVS interior administraion system integeration with SOA.We analyze the requirement of XMUCSVS business and the disadvantage of traditional distributed component architecture.And we point out the advantage of implementing XMUCSVS system integration by SOA.Then we research the business process with the design idea of SOA,and build some SOAs of different grain size using WINDOWS platform and web service technology.This is the solution of XMUCSVS system integration,which enables us keep up with the change of the business at minimun cost and the quickest speed.In the end,we analyze the problems of SOA and its development direction,and give the development prospect of XMUCSVS system.
