如何在业务系统之间进行数据交换，是所有企业在信息化建设过程中必须要解决的关键性问题。为了消除企业的“信息孤岛”问题，打破业务系统间的信息壁垒，加强发掘数据应用的潜力，提高信息共享利用的效率和水平，文中设计了一套基于XML消息的安全数据交换平台。该平台采用了XML消息作为交换媒介，以Web Service作为交互方式，并采用了数字信封作为加密与解密手段，保证了业务系统间数据快速、安全、可靠的交换。文中的研究工作在信息系统的数据交换中有一定的理论与实用价值。目前，该平台已实际应用于南方电网中，并取得了良好的应用效果。%How to exchange data between business systems is a key problem which has to be solved in the implementation of enterprise in-formationalization. In order to solve the problem of"information island",and break down information barriers between business systems, and strengthen the potential of exploring data application,and improve the efficiency and level of information sharing,a secure data ex-change platform is designed based on XML message. The platform uses XML messages for a medium of data exchange,and uses Web Service for communication mean,and uses digital envelope for encryption and decryption,which ensures the message exchanging between systems quickly,safely and reliably. The research has definite theoretic and practical value in the field of data exchange of information system. The platform has been used in China Southern Power Grid,and achieved good result.
