RE:  XML vs relational database
The SQL standard certainly continues to define this set of views and 
tables (known as the Information Schema).  ISO/IEC 9075-11:2003 is 
the most recent edition, but a 2008 version is expected by 
mid-2008.  See your countries national standardization body for a 
copy or go to http://www.ansi.org and click on the Web Store link.

As Mike said, this has been available for a Very Long Time (it may 
seem like 20 years, but it was in the 1992 edition of the standard 
that the Information Schema came into being),

As a matter of fact, the call-level interface (CLI, of which ODBC is 
an implementation) defined in 9075-3:2003 (soon to be 2008) defines 
an API to get the same information without having to do all those 
annoying SELECTs ;^)

Hope this helps,
