The Study And Application Of A WEB Development Framework Based On Task

With the rapid development of information and network technology,the development of web application system,especially the enterprise web application system,has become an important field of software development.The enterprise web application system always requires an excellent architecture, higher development efficiency,more accumulation of the technology and the experience,more rigorous management of the project.But the traditional development modes of web application system do not commendably meet those requirements.So some developers bring forward a new development mode of web application system that is based on the web application framework,and developed some characteristic web application framework.But,much research of framework technique emphasizes on catholicity and currency,which makes stress on reuse of coding.It's still unusual to study or apply framework technique in some specific domains. This paper brings forward a new web application framework whith named TaskFrame aiming at the enterprise web application by deeply analyzing the common characteristics of web application system.This framework is based on J2EE platform and adopts the idea of MVC patten.This framework is Different from common web framework.It aims at the specific domains that there is large quantity of pages for inputing and outpting data,and these pages can be quickly completed with the function of authorization management,data verification,page separated,sorting,searching and printing by using this framework.It brings forward a concept of task which forwards development,and all operation in web system such as views showing and button's operation is task.The task makes use of data dictionary and decides the process of data handled,view showing and the customer's authorization.It gathes a support develop platform which can complete task definition,authorization definition,menu management,so the developer can designs out web pages with consistent style and perfect function only needing little codes. The main problems solved in this dissertation are following below: â‘ A web application framework based on J2EE platform with the ideas about software architecture,framework,design patten,and object-oriented is designed and implemented. â‘¡Referencing the framework,a support develop platform with task definition,authorization definition,andmenu management which simplifies the enterprise web application is implemented. â‘¢The System of MIT-ERP is successfully implemented with the framework,and the realizing result is analysised. The research result of this dissertation can be used to any enterprise web application system's development.By adopting this web application framework,the developer can acquire clear architecture and higher development efficiency.
