Research And Implement Data Integration Layer Of Education Management System Based On SOA

After many years of information technology, departments of schools are established in accordance with their demand for information management systems. The lack of unified management and design of initial construction results independent building applications, the lack of uniform standards, various departments of the application of its own system. SOA (Service-Oriented-Architecture) and Web Services technology to solve such problems is the newly developed design concepts and structure that can better solve the education management system in collaboration between business and information-sharing and other issues, loosely coupled systems to achieve academic and high expansion.The thesis discusses the design schema of education management system based on the Virtual View Data Integration Layer (VVDIL) by in-depth study of SOA and Web Services technology, for the current education management problems. The core idea of the schema is "reliable access and update data, simplify and improve the overall SOA architecture".The thesis analyses the SOA application management system and the status quo at home and abroad, points out that the current bottleneck in data management is one of the factors to reduce SOA complexity, in order to establish the goal of thesis's research and design- create common data management methods and achieve the greatest SOA effectiveness. And then, analyses SOA framework of the current management system in the education management, the demand for data integration and the current needs of mainstream data integration framework and points out that its traffic, data integrity, data access performance to consider is proposed in SOA to create a robust data integration layer. By analyzing advantages and weaknesses of Data Warehouse, the federal database and data integration middleware program, finally, we determines creating a virtual view data integration layer (VVDIL) in SOA reference to middleware architecture with real-time data integration and scalability advantages. Then we research the main design problems of VVDIL: VVDIL architecture, virtual view, global data dictionaries, caching mechanisms, and SQL query decomposition algorithm and the results of a detailed mechanism for the collection and description of SOA architecture to solve data management system bottlenecks.VVDIL is used in the Education Management system. The thesis discusses the related technology of VVDIL in the system. By the test, VVIL can play loosely coupled, low complexity, high-expansion of the advantages of existing systems with seamless connectivity, but also play a VVDIL in the data integration effective control and allocation of areas, improve the ease of development.
