Dear all,

I am looking for a RDBMS (Relational Database Management System) that provides management of XML data in a relational fashion.
I found the IBM DB 2 XML Extender. However, I am not sure if this system is already in use (because the latest release was in 2003).
I would be very grateful to you if you could help me to find what I am looking for.

PS. For RDBMS handling XML data, we find two categories: XML-enabled systems (they store XML data using a special data type like BLOB, CLOB,...), or the native XML systems (which stor XML data in its hierarchical structure, so the fundamental unit of storage is XML document). So, I precise that I am looking for an XML-enabled system and NOT a native XML system.

Thanks in advance.

Best regards,
