DataDirect XQuery is a high-performance Java component that implements both XQuery and the XQuery for Java API, used to query XML and relational data together. It supports most relational databases (SQL Server, IBM DB2, Oracle, etc.), runs on any Java platform, and is easily embeddable into almost any Java program. DataDirect XQuery works with any J2EE Application Server, although no application server is required. This tutorial shows how to use various relational and XML tools in Stylus Studio that use DataDirect XQuery to further simplifies relational and XML data integration.
