[BangPypers] NoSQL (was: BangPypers meeting February 2011)

[Anand Balachandran Pillai]

I am sure many of you must have gone through this discussion, but sharing
it anyway since I liked the analogy he makes with SQL against NoSQL
compared to transmission in cars.

It might be a cliche, but I kind of feel the current "NoSQL movement"
is simply a case of "The grass must be greener on the other side".
