Decomposing and Storing XML Based on Relational Databases
Zou Jing · Computer Engineering and Science · 2005
This paper gives a scheme for decomposing and storing XML in relational databases. First, through the analysis of XML syntax, we define the XML tree: all of its nodes have the same format. The XML tree helps to map an irregular XML document to a regular XML tree. Second, we define the relation XSR to store an XML tree to RDB. Data integrity is guaranteed, and in the mapping process, an XML document will be mapped to just one table other than multiple ones. This scheme is a common scheme. It can be used to process any XML document.
