Research on technology of XML data management based on RDBMS

Although XML (extensible markup language) is a special markup language for internet, it has become the standard for data representation and exchange on internet, it is a new way with good future to manage data. The relational database management system (RDBMS) has been developed as a mature and widely used technology. Comparatively, they both have advantages and disadvantages on data management. Combing XML and database to manage data has been become a hot spot for database researchers, based on the research of the technology which combing XML and database, a implemened framework of XML data management is proposed, with utilizing some special mapping methods, parsing the schema files or DTD, and then producing the corresponding relational schemas to store and manage XML data in a RDBMS. Users can manage XML data by XML operations without awaring of anything about the RDBMS. This framework is easy to be extended in the future because of its flexible structure.
