XISS/R: XML Indexing and Storage System Using RDBMS* Philip J. Harding, Quanzhong Li, and Bongki Moon   View Paper (PDF)   Return to Semistructured Data Management (Session D1) Abstract We demonstrate the XISS/R system, an imple- mentation of the XML Indexing and Storage Sys- tem (XISS) on top of a relational database. The system is based on the XISS extended preorder numbering scheme, which captures the nesting structure of XML data and provides the oppor- tunity for storage and query processing inde- pendent of the particular structure of the data. The system includes a web-based user interface, which enables stored documents to be queried via XPath. The user interface utilizes the XPath Query Engine, which automatically translates XPath queries into efficient SQL statements. ©2004 Association for Computing Machinery
