This month's Teradata magazine has a very interesting article by Matt Zenus explaining how the Teradata OLAP connector works.  Basically, this gives you the ability to do OLAP style analytics right in your Teradata database and access the results using the MDX query language.  You can read Matt's article here: http://www.teradatamagazine.com/v11n01/Tech2Tech/Direct-Access/.

Also, in case you didn't see this, Teradata posted some pretty good numbers for Q4 and the year as a whole: http://www.theregister.co.uk/2011/02/10/teradata_q4_2010_numbers/.
