Study On System Integration Of Campus Network

The emergence and development of campus network is to meet the needs of social and educational informationization. The application of campus network is the result brought by the further development of information technology, the outcome of modern high technology, the product of the combination of educational informationization and information technology.However, because of the whole planning & technical choice, information silo appears in campus network system integration prevalently now, and it leads that information can't be shared, data building repeated et al, brings about some difficult in communication and communion between systems. Thereby, how to choose the right integration technology become the emphasis and hotspot in research of campus informationization. Traditional EII adopts CORBA, DCOM, EJB, and so on, which has an advantage in setting up connective, closely coupled distributed system and enterprise-internal information system integration, but are difficult to develop information-oriented, loosely coupled distributed system and dynamic integration of inter-company information system. Information integration of campus network is a special case of EII(enterprise information integration), It has the same problem.In the thesis, the author studies the present situation of campus network integration, its practice and existing problems, compares a couple of common integration technology and methods. The MDI-based information integration is model-driven, providing enterprises with the ability to have a real-time access to all integrated heteroideous information sources. Web services, as a loosely coupled subassembly, is self-embodied, self-descriptive and modularized application. It's platform and programming language independent, can be released and located, executed via web, which ensures the easiness-to-use, reusability and flexibility of model-driven information integration. The thesis deems combination of MDI and Web services can reduce the coupling degree of application system and information sources, makes the management and access to information much more convenient and easier.In the thesis, first introduces the correlative basic theories, analyzes the original information system and the inter-system relationship in universities, designs the framework of information system integration, builds integration model of campus network system. In realizing integration, the concrete developing process of system integration is provided by access to information system integration and to information integration of Web services configuration. Finally, through the theory and example, the author lists a couple of problems which may be caused while applying the integration methods explained in this thesis, and proposes the advice of campus network system integration construction.
