In this paper,an architecture is proposed to implement the conversion bet ween XML and DBMS ,and XTRANS,based on this architecture,can store XML data to the relational database and publish relational data as XML file.

• 该文提出了一种XML与传统关系数据相互转换的系统框架,XTRANS就是在此基础上实现的一个XML与关系数据的转换系统。 系统借助一个映射文件来定制系统的转换细节,能够实现保序的转换。
