Path-based XML Relational Storage Approach

Abstract As an important medium for the description of product information and data exchange, XML(eXtensible Markup Language) is widely used in the network supported collaborative design. How to store and query XML data will directly affect the performance of collaborative design system. Compared the advantages and disadvantages of existing XML data storage technology, a new path-based XML data storage method using relational database is proposed. This paper gives the specific storage mapping algorithm. The different XML documents are stored using a fixed relationship model and not limited by the document DTD(Document type definition). The XML data stored using the method have unique advantages such as simple structure, small volume and easy to query processing. Good data processing is helpful for improving the efficiency of collaborative design system.
