Adaptive storing and querying XML data in RDBMS

Introducing XML support in relational database has been of keen interest in image processing in the past few years. Shredding approach, which shreds XML data into relational tables, is proposed to speed up query on XML documents. As XML usages for both data-centric and document-centric applications are very popular now, the shredding approach provides limited support for the document-centric or ordered nodes documents. Providing native XML is proposed for good query performance, the document is stored as a unit in this approach. However, XML schemas for real-life applications are complex, the Shredding approach or native XML support is not fit for all applications. This paper proposes an adaptive storing and querying approach on any XML data. Experimental results from our prototype system implementation highlight the correctness and efficiency of our solution. © 2008 by Binary Information Press.
