Research And Application Of E-Government Systems Based On MVC

With the development of the Computer Science and the Information Technology, the network has become a kind of basic infrastructures in our daily life. Kinds of systems based on network appeared and the E-GOV System is one of them. The E-GOV System can organize all the information effectively, share them among all the departments, and improve the work efficiency greatly, so it is a kind of most important way to build the E-GOV. The content of economy and society which is developing quickly has decided that the E-GOV System should also satisfy the change of the active government. So it has been a pressing problem how to make the E-GOV System much more extensive and reusable.The MVC pattern is a kind of layers pattern. It separates the whole structure into several layers: Model, View and Controller. All the layers exists separately, the interface among them is clear and make the coupling lowest. So this characteristic satisfies the need of the E-GOV System. Especially it bases on the J2EE platform which provides kinds of components and containers which the developers can use to be the roles in MVC. And it makes the development much easier and improves the efficiency greatly. Struts is a kind of framework based on the J2EE platform and realizes the MVC pattern. Besides these Struts give us large tag libs and improves the support about View.This paper introduces the advantages to apply the MVC to the development of E-GOV System development firstly. Then analyze the structure, the details of the MVC pattern and the main parts of Struts framework which realizes the MVC pattern. At last based on the Shanghai Visa and Passport Management Information System, a subsystem of the Shanghai E-Gov System, the paper introduced details how to use the MVC pattern during the development of the systems.
