对几种软件集成方法进行了理论比较 ,介绍了COM (组件对象模型技术 ,ComponentObjectModel)在三峡决策支持系统 (DSS)中的实践应用 ,描述了COM的使用和应用COM后系统的升级和扩展方法。实践表明 ,COM在大型软件开发中的应用不仅可以加快系统的开发速度 ,增强模块的重用 ,改善系统结构 ,而且可以极大地方便系统以后的维护、升级和扩展
Several software integration methods are compared theoretically. COM (Component Object Model) and its application in the Three Gorges Decision Support System (DSS) are introduced. The COM application and the application of COM are introduced. . Practice shows that the application of COM in large-scale software development can not only speed up system development, enhance module reuse, and improve system structure, but also greatly facilitate future system maintenance, upgrade and expansion
