There seems to be a lot of action in the data warehousing space.
Last year, we had EMC buy Greenplum: http://www.emc.com/about/news/press/2010/20100706-01.htm. We then had IBM acquire Netezza: http://www.netezza.com/releases/2010/release092010.aspx. Then in September, we saw Aster Data raise $30 million in a C round: http://www.asterdata.com/news/100922-Aster-Data-Series-C.php and get a new CEO in Quentin Gallivan.
2011 has started out in the data warehousing space with Kognitio announcing a funding round: http://www.kognitio.com/kognitio-secures-funding-from-cfp-founders-investments and Microsoft announcing the departure of Bob Muglia: http://www.microsoft.com/presspass/press/2011/jan11/01-10steveb-mail.mspx.
Will 2011 be an interesting year? You bet. I think there will be more action in 2011 than there was in 2010. The economy is improving, companies have cash to spend, work needs to be done.
