The Research And Implementation Of Network Education Management Information System

The popularization of education and lifelong study have accelerated the development of network education. Compared with the traditional classroom teaching, the network education is flexible, open and selective. It has become a branch of education field which developed the most quickly. Along with the higher development of network education, one of the critical problems is how to construction a superior Network Education Management Information System (EMIS) which in perfect accord with the related standards in network education.This paper is just based on such topic and set the Network EMIS of College of Network Education of Central South University as an example. The system framework, function, implementation and other related problems are researched in this paper. It analysed the main technique solutions used in the constructions of Network EMIS of some of our national universities and colleges. By analysing and comparing the development of platforms and models of different choices in such kind of system, it can be found that the present set of development of software does not reach the related standards. Meanwhile, new requirements in performance and security of Network EMIS have also been put forward.Connecting with its practical needs and basing on the analysing of its characteristics and present states, this system structure employs B/App/D structure N-tier as its solutions: WebLogic as its application server, SQL Server as the database server and JSP as the dynamic Web technology. This paper does some helpful research from the following aspects: firstly, it expounds the detailed process of constructing the framework which is suitable for network education by using J2EE series technology and classical MVC construction modle. Secondly, it introduces the duplex authenticated solution in the system to solve the security of link layer and authentication of identity. Then, it elaborates the steps of development and related problems in application by using OpenSSL to build a small CA authentication centre. Thirdly, it uses Oscache technology to improve the performance of the system, does compare tests by Jmeter and analyses the result of the whole performance of those optinal technique solutions and choosed technique solutions. It proves that the technique solutions we choosed can meet the realistic requirements of network education.Basing on the analysing of the present EMIS, this study puts forward a new set of technique solutions, does the research in detail on the feasibility of the adopted technique solutions, the design target, the structure model, the framework design and implementation.
