If you follow the Gartner Magic Quadrants, Teradata has provided a copy of the 2011 Gartner Magic Quadrant for Data Warehouse Database Management Systems on their website.  Here is a link to it: http://www.gartner.com/technology/media-products/reprints/teradata/vol3/article1/article1.html.

If you pay attention to this space, the Gartner Magic Quadrant report is worth a read.  Donald Feinberg and Mark Beyer do a good job of analysis.

A few things I noted:

1. Teradata is of course in the leaders quadrant and gets good reviews.  Too bad there is no mention of Teradata Business Intelligence Optimizer (TBIO).  I think it will make an impact on the BI/analytics front for Teradata.

2. When compared to the 2010 version of the Magic Quadrant, SAP's acquistion of Sybase seems to have been a positive for Sybase.

3. Microsoft is now in the Challengers quadrant whereas last year they were in the Leaders quadrant.  Gartner says that part of this was the release of PDW came after their cut-off, but I really think Microsoft should be in the Leaders quadrant as they are innovating well.

4. IBM's acquisition of Netezza does not seem to have done much on Netezza's positioning so far.

5. EMC's acquisition of GreenPlum has helped move them from Visionary last year to Leader this year.

6. HP drops out with NeoView being end of lifed.  No real movement with Vertica's positioning.  Will be interesting to see what effect the HP acquisition has on Vertica.

7. Aster Data is still in the Visionary quadrant but seems to have more ability to execute versus last year.  Their new CEO and round of funding they got last September are making a difference.

8. Kognitio makes a nice move from a Niche Player last year to a Visionary this year.  Their new Pablo product will also make an impact for them on the BI/analytics front but so far Gartner is not taking that into account.  Also, Kognitio recently got a round of funding and is expanding which is a good sign.

9. ParAccel moves from Niche Player last year to Visionary this year.

10. Ingres moves from Nice Player last year to Challenger this year.

11. Oracle and IBM are also in the Leaders quadrant with Oracle ahead of IBM but behind Teradata.
