The social web generates terabytes of unstructured, user generated data, spread across thousands of commodity servers. The changed face of web based applications forced to invent new approaches to data management. The NoSQL databases were created as a mean to offer high performance (both in terms of speed and size) and high availability. They share the goals of massive scaling \"On demand\" (elasticity). Hence NoSQL is best suited solution to the big data needs posed by the evolving web application. With the advent of newer NoSQL technologies each day, developers face a serious issue in selecting the best suited datastore for their application as each of them place very different demands.
