I have been working with warehousing for a while now.

I am intrigued by Columnar Databases and the speed that they have to offer for data retrievals.

I have multi-part question:

How do Columnar Databases work?
How do they differ from relational databases?
Is there a trial version of a columnar database I can install to play around? (I am on Windows 7)
