NoSQL

Came across the term "NoSQL" from one of the mail threads in WSO2 carbon-dev mailing list.

What is NoSQL, I didn't know it. Even wondered whether its a typo :p... can't obviously be. So googled;

Here's the wikipedia intro (until I read more detailed stuff later);

"NoSQL is a movement promoting a loosely defined class of non-relational data stores that break with a long history of relational databases. These data stores may not require fixed table schemas, usually avoid join operations and typically scale horizontally. Academics and papers typically refer to these databases as structured storage.
Notable production implementations include Google's BigTable and Amazon's Dynamo. However, there are also many publicly available open source variants including HBase and Cassandra."
