Web环境下数据过滤方法研究

Research on Web-based Information System Data Filtering Method

网络技术的发展使得Web环境下的信息系统迅速增加。传统开发模式中,系统数据过滤代码不能复用、处理效率低,并且开发工作量大,影响系统开发效率。本文提出了新的数据过滤方法,把数据过滤程序与系统功能页面分离,将过滤程序文件布置到服务器端。要过滤的数据由数据过滤函数一次性进行数据过滤并反馈数据过滤结果以及提示信息。该数据过滤方法实现了信息系统数据过滤的灵活定制和软件复用,减少了开发人员的重复工作。

The development of networking causes the information systems to increase rapidly under the Web environment. In the traditional development pattern, the filtering codes of system data can not be reused and he processed in low efficiency so that the system development efficiency is affected. This article proposes a new filtering method which separates the data filtering program from the function page of the system and＇ arranges the filtering program to Server. The data filtering function filters the data once only, then feedbacks the result as well as the prompting message. This data faltering method realizes the flexible customization of the information system data and software reuse, which reduces the porsonnel＇s repetition work.
