摘　　要：数据交换是解决信息孤岛问题的实用方法,但如何实施灵活有效的数据交换一直是研究的难点。基于此,提出了动态服务的数据交换方式来克服原有单一、固定的交换缺点。依据交换系统的现状,首先给出了静态服务库、动态服务库和静态交换系统、动态交换系统的概念;然后提出了动态服务的交换模型,并给出了交换的方法、原则和实现过程。最后,结合具体的应用实例,验证了模型的灵活性和有效性。Data exchange has been an efficient and practical approach to solve information island, but how to implement flexible and valid data exchange is still an open issue. This paper proposed a data exchange algorithm based on dynamic service to overcome the shortcoming of the original, single and fixed data exchange. First, gave the concept of static service database, dynamic service database, static exchange system and dynamic exchange system based on the analysis of current exchange sys- tem. And then proposed data exchange mode/ based on dynamic service, and detailed specific design and implementation process. Finally, gave an application example to show the flexibility and validity of model.
