一种Web应用框架的研究与实现

Research and Implementation of Web Application Framework

软件框架是目前产业界实现大型软件快速开发的关键,也是学术界研究的热点。文中分析了Web应用三层架构的实现方式及其特点,提出了一种新的Web应用框架。该框架采用"面向接口"的设计思想,通过构建业务逻辑接口层实现了表示层和业务功能层之间的松散耦合,通过构建数据访问接口层实现了业务功能层和数据存储层之间的松散耦合;以某大型制造企业的工时管理系统中用户登录功能模块为例,详细阐述了采用此框架构建Web应用的具体过程。该框架可为有效实现基于Web的应用软件的开发提供帮助。

Software framework is the key to fast developing large - scale software in industrial filed and is also hot spot which the academic circle is studying at present. Analyzes the way to realize three- layer structure in Web application and their characteristics, proposing one kind of new Web application framework. This framework, employing the design notion of interface- oriented, has realized loosely coupled between presents layer and business layer by virtue of constructing business logical interface layer, and between business layer and da- ta layer through constructing data access interface layer. Finally,take the functional module of user login in time quota management system of a large - scale manufacturing company as an example to elaborate details on construction of the process of the Web application based on the framework mentioned above. This framework will be instructive for realizing application software＇s development based on Web effectively.
