摘　　要：分布式计算技术在软件开发中得到了广泛的应用,它使复杂的大型网络应用程序在结构上更清晰,更易于开发。组件对象模型COM(Component Object Model)和分布式组件对象模型DCOM(Distributed COM)是微软软件体系结构中使用的分布式对象技术。通过分析基于COM/DCOM组件技术的分布式计算的基本原理,总结了开发使用COM/DCOM组件的基本方法和三层分布式应用程序的实现过程。最后给出了一个用DCOM组件构造的三层分布式应用系统实例。The distributed computing technique is now widely used in software development, which makes the developing of large complicated network application more systematical. The Component Object Model - COM and Distributed Component Object Model - DCOM technology is one of the distributed computing techniques presented by Microsoft. This paper analyzes the distributed computing Architecture and principle based on COM/ DCOM in detail, and puts forward some implementing methods of COM/DCOM components and 3 - tier client/ server application. Finally, illustrates these ideas by a 3 - tier client/server application based on DCOM compo- nents.
