Abstract: During the process of relational database integrated to XML, relational data is translated for once by static transform method. This method can not meet the translation needs of special relational data in some applications. In order to realize dynamic translation, this paper proposes a dynamic translation system based on the universal mapping model of static translation system and gives the relevant dynamic translation algorihtm. The efficiency and generability of this algorithm are verified by examples.

摘要： 在关系数据库向XML集成的过程中，静态转换方法对关系数据进行一次转换，无法满足实际应用中某些特定关系数据的转换需求。为实现动态转换，在静态转换系统通用映射模型的基础上提出动态转换系统，给出相应的动态转换算法。通过实例验证该算法的有效性和通用性。
