Application Research Of SOA Based On Web Service

With the rapid development of information technology, the request of software technology must be improved. The early software(computer) mainly helps people do some repeated and simple works, little by little, it plays the role of information processing and goes deep into many fields. Departments in enterprise publish information and hold OA system based on computer network. People do this for its convenience. More demands are put forward, software faces new challenge. First how share information among departments or enterprises. People provide the same communication protocol so that information flow is liquidity. Second enterprise changes the applications according as its development. To meet the changes software must be agility through little maintenance cost. The conception of Web Service is advanced. Web Service resolve the problem of sharing information. But Web Service cannot resolve the problem of Changing on Demand. The conception of SOA(Service Oriented Architecture) is advanced, and SOA can resolve the problem of changing on demand. So Web Service and SOA combine to solve the current problems, which is efficiency. In fact the application research of SOA based on Web Service become more popular.SOA describe an excellent perspective, but many new problems are produced when we implement the application based on SOA. Recently many software companies and study institutes focus on SOA, and provide many solutions based SOA. The study work are developing. In this paper the application research based on SOA is developing as follow:Firstly, Service-Oriented Analysis and Design(SOAD) is discussed. Through comparing technologies of software development, we conclude that many technologies combine to resolve the Service-Oriented Analysis and Design.Secondly, through comparing the solutions of the application research on SOA based on Web Service, we discuss a solution based on open source software.Thirdly, a prototype of the school information manage system is implemented. From that we can prove its availability, and describe the method of SOA development.
