Re: [xquery-talk] The State of Native XML databases>> On the relational-XML
database side, both Oracle 10g and Microsoft SQL Server 2005 support XML
integration in the same manner as DB2 9, extending the relational model to
include an XML type when defining column types for a table.
Oracle, Microsoft SQL Server and IBM DB2 support the XML type, but there are
differences in the architecture and storage engine they use for XML. Supporting
XML brought architectural changes when Oracle moved from 8i to 9i. Microsoft SQL
Server 2008 adds a new HierarchyID system type for operating with
tree-structured information. The DB2 architecture changed between versions 8 and
9.
This DB2 magazine article explains DB2 version 9 changes for XML:
