XML Feeds vs SQL Queries

<span style='font-size:10.0pt;
font-family:Arial'>Given a choice for implementing dashboards that support
near-real time notifications, would you implement XML feeds or SQL queries and
why?<o:p></o:p>

<span style='font-size:10.0pt;

<span style='font-size:10.0pt;
font-family:Arial'>Not that it changes the question, but I am told that MS SQL
Server and the ASP design is set up to push one toward SQL providers and away
from using XML.  I see lots of
articles for implementing either, but the claim is that performance is tuned
for the SQL sources not XML.  
My intuition was that for dashboards that don't update the
database, (eg, read only), that decoupling and using
the feed model was a better use of client-server/network resources.<o:p></o:p>
