The Developing Technique of client/Server System

该文主要讨论了客户／服务器系统的结构，广泛应用的原因及其优点，并以ＳＱＬＳｅｒｖｅｒ的存储过程和触发器，ＰｏｗｅｒＢｕｉｌｄｅｒ为例说明功能强大的ＤＢＭＳ和前端开发工具保证了客户／服务器系统的优越性能。并介绍了Ｐｏｗｅｒｂｕｉｌｄｅｒ的一些技术特点，客户端应用软件在实际应用中的几种查询方式，以及实现主／明细窗口的技术要点，并用ＰｏｗｅｒＢｕｉｌｄｅｒ建立了一个通用的、主表可更新的主／明细数据录入窗口的父类对象。

This paper discusses the structure of the Client/Server system. With examples such as PowerBuilder, the stored procedure and the trigger of the SQL Server. we demonstrate the powerful DBMS and de veloping kit which warrant the high quality of the Client /Server system.The paper introduces some features of PowerBuilder. In this paper,we discuss the technique in realizing this kind of window and build a parent object of a general master/detail data-inputing window with its master table updatable.
