Program With XML for DB2, Part 2: Leverage Database Support for XML in Your Application Architecture

Overview

XML's status in databases has changed in the last couple of years from a temporary worker to that of a first class citizen. No longer does it need to morph its identity in order to fit into the relational world. It proudly maintains its hierarchical heritage, even while exploiting the power and stability of the relational database world. In fact, some of its relational neighbors have adapted techniques that make them look like XML in order to exploit the richness of the hierarchical XML model. This paper showcases how the new XML storage and query environment plays into the XML data model. It shows how once the user adapt to the new XML-based application development architecture, the database schemas become much simpler and more natural.
