摘要
讨论了Internet环境下数据交换的特点,分析了一类在数据库间交换数据的应用所具有的特点,并在此基础上提出了一种独立于运行和开发平台的数据交换模型。该模型基于数据库间的直接连接,对应于一类广泛的数据交换应用。以一个可实际运行的原型系统为基础,详细讨论了该模型的体系结构、数据描述、数据交换通信协议(DECP)、安全性和半自动化等几方面的内容,并给出了实现指导。最后对进一步研究该模型给出了总结及展望。
At first, the features of data exchange on internet are discussed. Then the characteristics of a kind of data exchange applications between databases are analyzed. Based on these analyses, a new data exchange model is given, which is based on direct database connection, and is runtime and developing platform independent and can be applied to a broad kind of practical applications. Furthermore, different aspects of this model in detail are presented, including its architecture, data description, a communication protocol which is named DECP, secure mechanism and semi-automation. The guidance of implementation is also given. At last, some prospects of future work on this model are given.
