Abstract

A relational database is a table based system where there's no scalability, lowest data duplication, computationally overpriced table joins and issue in addressing complicated data. The matter with relations in relational database is that advanced operations with massive data sets quickly become prohibitively resource intense. Relational databases don't lend themselves well to the type of horizontal scalability that is needed for large -scale social networking or cloud applications. NoSQL has emerged as results of the demand for relational database alternatives. The most important motivation behind NoSQL is scalability. NoSQL is supposed for the present growing breed of net applications that require scaling effectively. This paper analyzes the NoSQL database that is the demand of the present large-scale social networking or cloud applications. The analysis of assorted NoSQL databases like Bigtable, Cassandra, CouchDB, MongoDB and Couchbase has been highlighted.
