摘要
提出了一种基于元数据的Web通用查询系统(GQS)。GQS引入元数据概念,并结合JDO、Servlet、JSP等技术手段,实现了一些通用性较强的查询模块,同时能够根据查询对象动态生成查询页面元素。此外GQS还扩展了查询定制等功能。相对于传统的查询系统,GQS的功能性、通用性、移植性大幅提高,并且很大程度地降低了系统维护量。
A web general query system （GQS） is proposed in this paper. Introducing the concept of metadata and developed with several technologies such as JDO, Servlet, JSP, the GQS is composed of some general query components and can dynamically generate the query pages according to the query objects. An extension, the customization of query, is added to GQS to complete its function. GQS leads to more transplantability and less maintenance.
