摘　　要：随着信息化建设的深入,异构数据库系统之间进行数据交换、数据共享的需求越来越突出。因为XML技术具有平台无关性、易于扩展、交互性好和语义性强等特点,可以作为异构数据库之间进行数据交换的标准。给出关系模式与XML模式之间的映射规则和转换方法,设计异构数据的抽取转换工具,该抽取转换方法具有通用性,易于扩展。With the development of information construction, the needs of data exchange and data sharing between heterogeneous database systems are growing. XML technology has the following char- acteristics： a platform-independent, and easily extensibte, interactive, semantic, can be used as the standard of data exchange between heterogeneous databases. Gives the mapping between relational schema and XML schema rules and conversion method, and designs the extraction of heterogeneous data conversion tool. The extraction conversion method has the versatility, and is easy to expand.
