2) Online Video Tutorials and Examples: XQuery and Updates

XQuery is perfect for integrating data and reporting information when the data needs to be represented as XML. But consider going in the opposite direction — what if your data source is XML? For example, say you've just received some inventory information as XML and you need to update your relational database to reflect the changes? Or, you've received insurance policy information as XML and you need to update the customer’s records which are stored in a relational database.

DataDirect XQuery enables you to update your relational data sources from your XQuery! It's easier than you probably imagine, and two free online tutorials explain how:

• Using XQuery with Relational Databases: See how to use DataDirect XQuery to insert, modify, and delete data in your relational database.
• Updating Relational Databases with XQuery: Example files show how use DataDirect XQuery to update data on your relational databases.
