With the development of Internet and XML, XML has gradually become a standard of representing and exchanging data on the Web. Researching the technology of XML data management plays an important role in applications based on the Web. To organize and manage XML data efficiently, several XML data management approaches have been proposed. Relational Database technology has been almost perfect and dominant in business data management area.Using relational database to manage XML data is a viable and effective manner.This thesis researches the relevant technology of XML data management, analyzes the characteristics of XML, and does a thorough research and discussion on the relational storage of XML data and the querying process. The primary tasks of the paper are as follows:First, we summarize and classify XML storage approaches. Second, we study on XML storage technologies based on relational database, and store the XML data into a relational database using Structure-mapping method. Third, we study on XML query technologies based on relational database, and do the query of XML data using XPath and Xquery. Finally, we study on some key technologies of XML index, finish the coding of XML data using Dietz-coding method.
