Storing XML Data in a Relational Database

The Storing XML Data in a Relational Database article just published by InformIT.com describes the various methods you can use to store XML data in an SQL database. I've also tried to explain when it would be appropriate to store XML data in a database and when you'd be better off using the traditional relational database model. The rest of the article details the procedures you can use to insert, query, retrieve and modify the stored XML data.
