摘　　要：介绍了M IDA S三层分布式体系结构,分析了由客户端、应用服务器和数据库服务器三部分构成的体系结构模型的特点及其间数据处理流程.结合某企业电器设备计价管理系统对于内部网络复杂性和及时性要求,给出了便于实现的两种具体方法:基于A ctiveX和基于Soap的W eb方案.分析、比较两种方案的优缺点,得出采用M IDA S的W eb方案是一种较为可行方法的结论,并对M I-DA S执行效率问题进行了讨论.This paper, firstly, introduces a three-tier application based on MIDAS. The properties of MIDAS system frame, which are composed of client server, application server and database server, and data processing flow is analyzed. Then it illustrates two methods including MIDAS and Soap Web with the electric equipment management system. After comparing the advantages and disadvantages between them, the conclusion that it is more available to adopt the method of MIDAS in this management system is got. Finally, execution efficiency problems with MIDAS system is discussed.
