Network Test System Architecture Based On Soa Technology

With the development of the higher education and the reformation of the education system, more and more new university areas are established. These make the examination more and more complicated. The traditional method which makes use of paper and pens can not satisfy the effective demand, but computer science bring the opportunity to a new examination method without paper. Now more and more examinations chose the computers as the examination tools. At present, computer examination systems are mainly of two kinds, a stand-alone system and a network system. However, these computer examination systems have their own limitation. For example, they do not utilize existing multimedia objects. Under this background, the university put forward to establish a new computer network examination system. And this paper describes the design of this network examination system based on SOA.This paper combined the scientific management method and modern network technology, adopted the service-oriented architecture, applied advanced technology such as J2EE, GRID SERVICE, and finally completed the functions which included the foundation of test questions database, the test paper's automatic generation etc. Nowdays, this new network examination system has been run and all of the functions are performed well.My works are as follows:(1)The researching background and the developing trend of network examination system is summarized. All kinds of integrated technologies are researched. After the detailed technological analyzation, the system finally should be compatible with SOA. And this network examination system based on SOA will be designed making use of GRID SERVICE.(2)In accordance with the exploitation flow of software engineering, the requirement analysis, general design and detailed design process are carried out. In the part of requirement analyzation, the system is divided into two partation, the integration platform and network examination based on the platform. Then the data flow diagrams are founded. During the process of general design, the software structure diagrams and the hardware environment are researched. Then the design process that net examination system are encapsulated to GRID SERVICE is described. Finally, the network examination system are put to use.(3)During the design course, the key technologies such as the selection of integration platform, the management of SOA, the encryption and management of database are solved.The SOA-based network examination system is of great practical and theoretical significance in the school examinations. At the same time, the network test system has also become an opportunity of information systems integration. The integrated information platform, which is built by SOA, provides a way that all kinds of software of the schools share their resources.
