一种基于数据窗口的通用查询对象设计

Design a Common Query Object Based Datawindow

信息查询是信息系统中不可缺少的环节 ,普通的查询方法只是针对某一个具体的主题。考虑到查询结果一般都以报表形式显示给用户 (PB中一般用数据窗口显示 ) ,这里利用显示查询结果的数据窗口 ,设计了一种基于数据窗口的通用查询。真正体现了面向用户的思想。

Information query is necessary in an information system. A common query method is usually relative with one provided subject. Considering the result of query is usually showed for user by reports (in PowerBuilder always using datawindow), this paper has designed a common query based datawindow by using the datawindow which will show the result of query.
