PB查询软部件的设计与实现

The Design and Realization of Soft Components Working for Inquiry Based on PB

查询是使用数据最主要的方面,一般MIS系统中,相应模块设计工作量所占比重也很大。现有的查询都是针对具体的数据表,在实际应用中,查询模块的设计仍然很复杂。本文介绍了基于PowerBuilder的查询软部件的设计与实现方法。在使用时即插即用,只要做一些简单的参数设置,无需改变程序,就能完成MIS系统中查询模块的设计。

Data query module plays an important role in Management Information System.However,ordinary programs working for data query just aim at the given datasheets and do not have the versatility.This paper introduces the design and realization method of the soft components for inquiry based on PowerBuiler.We call it soft components for data query by which people can implement the design of query module without chanigng any codes.
