摘要
随着软件系统开放性的日益增强，数据交换技术已成为越来越重要的一个研究课题。文章介绍了系统实现中采用的数据交换技术，着重研究了基于消息传递的动态数据交换技术（ＤＤＥ）的实现机理和利用其建立数据交换应用的方法。在实际系统的数据交换中应用ＤＤＥ技术，在实践中获得了良好的效果。文中还研究了ＤＤＥ技术的扩展，即对象链接与嵌入（ＯＬＥ）的原理和实现。
Along with the openness of the software system, researches on data exchange become more and more important In this paper, We introduce several methods to exchange data in information systems while put our emphasis on the principle and implementation 0f Dynamic Data Exchange (DDE) technology. We apply DDE in the implementation of a practical system. We also study the principle and implementation of Object Linking and Embedding (OLE) technology, which is the extension of DDE. Our conclusion is that OLE can not replace DDE completely although it has more functions. On the contrary DDE has its advantage it many applied envi- ronment.
