Research On The Performance Optimization Of Web Management Information System

With the rapid development of Web2.0 and great prosperous of the Internet Industry, increasing number of traditional applications has been transferred into Web application. In recent years, more users preferred Web based Management Information System (MIS) to traditional C/S system, because the new type of system can be easily accessed everywhere in the world if connected to the internet. As a result, to design a Web MIS with high performance based on existing technology is a valuable topic that worth in-depth studying.Nowadays, a plenty of studies are focused on the backend performance optimization of MIS, and most of the studies are effective. However, study on the frontend of MIS is not as popular as the backend. Internet companies both at home and abroad gradually pay greater attention to User Experience (UE). As an effective away to improve UE while at the same time promote MIS's performance, frontend study will be the key point of Web application in the next generation.This thesis makes use of existing frontend technology on studying the method of promoting MIS performance both in UE and system efficiency. In order to reduce the redundancy of user request and waiting time for response, this thesis proposes a model for Ajaxifying web page. Based on the thought of cache, this thesis designs a page cache model for hot pages in MIS. This cache model will further reduce system redundancy, what more, it will also alleviate the load of server. In order to reach higher speed of server response, this thesis builds a page parallel loading model. All this three models are based on the technology of Ajax, JavaScript, CSS and Comet. This thesis also summarizes the updating of Science and Research System, which lays a solid foundation for future system optimization.
