Design And Implementation Of Network Test Service System Based On SOA

Object-Oriented method are the dominant approach today for building an application's business logic. But the communication model between application programs using objects hasn't been so successful. A better approach is to explicitly model interactions between independent chunks of software as services, and makes use of SOA to design the service system. Web service is a development phase of SOA, whose technology bases on XML.Network test system is popular CAE software, consisting of modules such as identification authentication, automatic group volume, on-line test, examination room management, automatic grading and so on. It can take advantage of the education resources in reason and improve their efficiency. The design approaches current used for network test system are all application-oriented. Therefore, some problems exist such as repetition development, maintenance of multi-system, test function simple. The dissertation designed and implemented a network test system, applying service-oriented approach based on SOA and XML.The primary contents of the dissertation is as follows:1) The development status of network test system at home and abroad is introduced. The service-oriented design approach, the .NET development platform and the realization technology WCF on this platform. 2) The requirements of a network test system for skill test are analyzed. Based on the business process and the principle of design for service, SOA approach is used to build the service-oriented architecture. To deploy, combine and use the distributed business component, which is loose coupling and rough granularity. The boundary and interface of the service subsystem are also defined. 3) The specific design using UML is presented to the modules level. And the service-oriented architecture WCF programming as well as the key realization of XML serialization are discussed.
