DATE: 2008-10-14 (14:00 - 15:00)SPEAKERS: Matthias Nicola (IBM Silicon Valley Lab)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 many existing performance guidelines for DB2 also apply to XML data, additional performance considerations apply to XML. This sessions presents 15 XML-specific performance tips for DB2, illustrated with examples. This includes a discussion of common mistakes and how to avoid them. 10 of the 15 tips also apply to pureXML in DB2 for zOS.EXP. LEVEL: Beginner,IntermediateOBJECTIVES:Make the audience aware of XML specific performance issues and trade-offsEnable attendees to detect and fix XML performance issuesProvide concrete examples for queries, create index statements, table space settings, etc.Explain how to avoid common XML performance mistakes in DB2 9Explain how XML and relational can coexist and be used together without performance penalty
