The XML can be used from within stored procedures in the database or shipped outside through web servers or application servers. Since XSU can Your application architecture may need to use an application server in the middle tier, separate from the database.

The application tier can be an Oracle database, Oracle Application Server, or a third party application server that supports Java programs.

You can generate XML in the middle tier, from SQL queries or , for various reasons.
