Research Of General Web Component Architecture

Humans have come into Information Times, by growing of information technology and computer technology. It is necessary that E-Learning comes up in this times. Web systems have been wide used with the web prevalence. Web system developments have also been increased. The module of web system have great coupling with each other now. This lead up to a matter that the code of one web system could not be used by another one. The software developer have to spend much time in architecture design. Then they will have to spend a lot of time in coding and testing. So there is always a long period of web development. There will be too many people and too much money to cost. These increase the cost of development without fail. Aiming at this problem, this paper begin with operation reuse, research a web component architecture which orient-web system named WCA(Web Component Architecture). WCA is able to solve the problems of common architecture design and component reuse in Web applications. Further more, a integrated methodology of Web system analysis, design, coding and testing is added on it too. With the help of business reuse concept of WCA, the reuse of function service and system service add up to a solid reuse system for Web component. Based on the development of encapsulation and isolation thought of Struts and Taglibs, and web module trait of easily reused, WCA layout and adjust the interface of modules. In this way the concept of component can be well used in system service, logic disposal and operation function. Then an integrative web component frame can be well formed. It change traditional web modules into web current components which can be easily reused and transplanted by defining encapsulation rules and interface description of web components. Developing a new web system will be easy as playing building blocks when a lot of WCA components have been finished. And it will be easy in testing.
