摘要
简论了三层体系结构的概念、优势、数据流程以及基于COM技术的客户程序与应用服务器之间的通讯方式 ,介绍了三层体系结构方法在气象信息处理系统中的应用情况 ,并以雨量要素的编辑修改和某时段内降水总量的统计为例 ,详细阐述了三层体系结构应用系统的开发过程 ,在此基础上归纳出了用DELPHI 4开发应用服务器和客户程序的一般方法以及开发过程中应遵循的原则和技巧。
A brief discussion is made on the conception, advantages, data flow of the three layer structure, and the communication mode, based on the COM technology, between the application server and client programs. The application of the three layer structure method to the meteorology information processing systems is described through the examples of rainfall editing and rainfall summing in a period of time to explain in detaile the developing process of the three layer structure system. Based on it, the general method, the related principles and skills for developing the application server and client programs using DELPHI 4 are presented.
