The Educational Information Network Construction Of Qingyuan

This paper studies the basic education information network and metropolitan area one-stop information platform construction in Qingyuan, Guangdong province, from the construction of the database platform, design for network and security system, information technology platform applications development, system architecture selection of several aspects, to spread information to the construction industry in China education in practical way.Through demand and technical analysis, from the point of view of the reliability, advanced, economy, practice, and to reach the requirements of Guangdong Provincial Department of Education to form the special network requirements of building a network, this paper argues that the current network using VPN technologies, multiple access approach to building network system for the Guangdong Province, Qingyuan City Board of Education is the best choice. By safety, cost, network efficiency, network scalability, several considerations, this paper contains proposed network physical layer, network layer, application layer and so on, all levels of the full range of solutions.Based on more advanced design concepts, will Qingyuan Education not only a one-stop information platform built in the region of a benchmark type of site-based education, but also should be built in Guangdong, one of the region and the application service provider (ASP) and the data center (IDC) design concepts, fully taking into account the realities of education and educational development of the mainstream MAN to play the advantages of the system architecture, both advanced and mature, this proposed system, the system uses a typical the 3-N-layer B/S structure, using large databases to centralized data management. The use of middle-tier components to the user program and the database connection, isolated business logic to provide sharing and collaboration between the systems is the optimal solution.Considering the limitations and the lack of and constraints for information technology in education funding, this paper is also a bold attempt, and innovative use of telecommunications into cooperation with the ASP model, the use of basic education in Qingyuan, Guangdong Province and Qingyuan education information network one-stop information platform for all kinds of resources, through cooperation with Qingyuan telecommunications subsidiary, to develop a variety of industrial applications, and promote information technology education in Qingyuan construction. By Qingyuan education completed by the test of time over the years to verify the feasibility of the model, benchmarking, and achieved gratifying results. Finally, this project summarizes the experience and look forward to the direction of development of information technology in education and development prospects.
