IBM® DB2® for Linux®, UNIX®, and Windows® introduced pureXML® technology in Version 9. This technology allows you to store XML data in its native form, maintaining the hierarchical structure and permitting you to query it using SQL/XML and XQuery.

The methods and mechanisms for ensuring the integrity of XML data, however, are a bit different than the methods for traditional relational data integrity. In this article, you'll learn about XML data integrity in the context of DB2, and explore the various options you have to guarantee integrity in different scenarios.
