Abstract
XML table indexes provide a more efficient mechanism for searching data stored in aggregate form. XML table indexes are a set of tables created to project out in column form commonly sought metadata from stored XML documents. By projecting the data includes into column form, queries on the XML documents can be efficiently processed as they can leverage the enhanced functionality provided by the database tables. The XML table indexes may use aliases, partitioning, constraints and other functions to further improve query flexibility and performance.
