摘要
传统查询模块由于代码固定,不能根据用户需求自由组合查询条件,缺乏健壮性等缺点,已经不能满足信息系统对查询项目不确定性的要求。在研究各类信息系统查询特点的基础上,提出一种新的动态通用查询模块应该具备的功能,查询关键字动态的由数据库确定,查询条件由用户自由组合,采用ASP.NET和C#作为主要开发工具,利用XML文件跨平台交换的特点进行查询参数传递,实现了该模块。最后对系统的异常处理进行了阐述。
The traditional query module cant satisfy the information system query item＇s uncertainty due to its limitations in the respect of code mobility, free combination query item according to users＇needs and robustness. Based on the research of the characteristics of multifarious information system queries, the paper provides a new function which a dynamic general query module should have. The database ascertains the query key word, and users combine the query items freely The module adopts ASP. NET and C# as two main instruments, taking the advantage of cross - platform exchanging data transferring parameter by using XML file. In the final part, the paper gives the description of the management of some abnormal process.
