基于COM/DCOM的分布式计算研究与应用

摘要

The distributed computing technology is now widely used insoftware development, which makes the developing of large complicated network application easy. The Component Object Model-COM and Distributed Component Object Model-DCOM technology is one of the distributed computing techniques presented by Microsoft. This paper analyzed the distributed computing Architecture based on COM/DCOM in detail, and summarized some implementing methods of COM/DCOM components and 3-tier client/server application. Finally, and 3-tier client/server application based on COM components was given.%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变得易于开发。基于组件对象模型COM(Component ObjectModel)和分布式组件对象模型DCOM(Distributed COM)的组件技术是微软的分布式对象技术。通过详细地分析基于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COM组件构造的三层分布式应用系统实例。
