Whitepaper: Native XML Support in DB2 Universal Database

by Very Large Data Base EndowmentJan 01, 2008

DB2 Universal Database has been enhanced with comprehensive native XML support to overcome the limitations inherent in mapping XML to relational tables or CLOBs. XML documents are stored as type-annotated trees on disk pages, indexed with path-specific indexes, and queried with XQuery, SQL/XML, or a combination of both. Schema validation is optional and on a per document basis, which allows for flexibility and schema evolution. The native XML solution in DB2 is rounded off by XML support in utilities such as XML import/export and a visual XQuery design tool.
