摘要
设计了一种基于多表的通用动态查询用户控件并将其应用到查询系统中,克服了传统的静态查询方法具有的不灵活、可维护性差、复用性低以及基于单表的动态查询信息量小、数据项独立性差等缺点,方便用户查询到相关的数据项,给用户提供较详细的信息.这种查询方式不仅有利于用户比较、分析数据,同时有利于提高系统的开发效率.测试结果表明,该查询系统的性能较好.
Designs dynamic query control based on multi-table and uses in query system,solves some defects including poor flexibility,difficult maintainability and low reusability of the traditional static query method and less query information and the poor data independence in previous dynamic query method based on a data table,makes user query the correlative data items,and provides the detail information.The query method not only makes user to compare and analysis data,but improves the efficiency of the system development.The test result show the performance of the query sub-system is good too.
