15 best practices for pureXML performance in DB2 9

Here is a new document written by Matthias Nicola about XML performance using IBM's DB2 version 9.

DB2 9 introduces pureXML support, which means that XML data is stored and queried in its inherent hierarchical format. To query XML data, DB2 offers two languages, SQL/XML and XQuery. Additionally, DB2 9 has sophisticated XML indexing capabilities and support for XML Schema validation. While most existing performance guidelines for DB2 also apply to XML data, this article provides additional XML-specific performance tips.
