In SQL termns, a NoSQL database is a single table with two columns: one being the (Primary) Key, and the sencondth being the Value. And that's it, that's all the NoSQL magic.

You would use NoSQL for one main reason: scalability.

If your application needs to handle millons of querys per second then the only way to achieve it is to add more servers, and with NoSQL that's very cheap and easy. In contrast, scaling a traditional SQL database is much more complicated.

Only the biggest websites out there are actually taking advantage of the full NoSQL potential, ie Facebook, having thousands of servers running Cassandra.
