Abstract:

If you're a Java 2 Enterprise Edition (J2EE) developer, you'll want to preview the SQLXML technology, currently in development. Check out procedures to create an XML document, store an XML document in a relational database, retrieve an XML document from a database, and navigate an XML document with the SQLXML Java data type.
