用服务器端控件方式实现表单处理系统

Implementation of report processing system based on server-side components

实现了Web浏览方式的表单显示和录入系统,系统中设计了基于J2EE的服务器端控件,对表单中使用到的控件进行封装,具有良好的可扩充性和重用性,并且具有平台无关性,强调了组件化程序设计的优点和意义。表单数据交换采用XML方式,具有良好的通用性和开放性,可以方便和外部应用交互或结合。系统通过数据中间层与数据库交互,由数据中间层的控制保证了数据库的安全性、完整性、一致性和可恢复性等。

A report display and interaction system are implemented based on BS (browser server) model. This system has been designed into server-side components which are based on J2EE. The function which is used in the web form is encapsulated. As a result, the system is extensive, reusable and independent on platforms. In the system, advantages of component design philosophy are focused on. XML is used in the system so that it can easily interact with other application and has a common interface.
