When you exchange XML documents between different systems or applications, you may need a construct that ensures your applications will “understand” the XML documents that are being exchanged. And this is where XML schema comes into a play!
Let's spend some time in this post with the pureXML storage concept, discussing how DB2 stores XML documents in the database. You may think this is too theoretical; that it is something happening in the background that you don’t need to know. But give it a try!
Today we will discuss how LOAD and UNLOAD utilities and file reference variables can help you to overcome inefficiencies in XML document maintenance with standard SQL statements.
