RDBMS has been around since long. It is the founder stone of many application stacks. It provides the users with the best mix of simplicity, robustness, flexibility, performance, scalability, and compatibility. However the emergence of the cloud centric application poses a set of challenges to the existing RDBMS Vendors. The RDBMS are not so suitable to cater to some of the critical requirement of these new generation applications such as handling large set of unstructured data or providing elastic scalability. This results in emergence of a new set of document centric or resource centric databases which are non-relational in nature. Promising non-relational solutions include CouchDB, SimpleDB etc. The authors have explored and conducted few experiments with some of such databases.
