Status Updates From Seven Databases in Seven We...

I'm reading this with a book club at work. We use Postgres already, and I know SQL, but I learned a bunch from that chapter. Unfortunately I haven't been able to install Riak or HBase as easily. Also the book really is written for programmers, as it says. While I can figure out how to read most of the code in the book, I would have a lot of trouble writing it.

book is slightly outdated on Riak, but still seems workable as an intro, in tandem with Riak documentation.
