Oracle XML DB integrates XML storage and querying using the Oracle relational and object relational framework. It has the capability to physically store XML documents by shredding them as relational or object relational data, and creating logical XML documents using SQL/XML publishing functions. However, querying XML in a relational or object relational database poses several challenges. The biggest challenge is to efficiently process queries against XML in a database whose fundamental storage is table-based and whose fundamental query engine is tuple-oriented. This paper presents the 'XML Query Rewrite' technique used in Oracle XML DB.
