In this digital era, volume of data is growing very fast and become more complex in nature (structured and un-structured and hybrid). Volume of complex data sets generally refered as ‘Big Data’. To control and retrieve and analyze Big data only RDBMS is not sufficient and it looks traditional or legacy for Big Data. To handle the problem, traditional RDBMS are complemented by specifically designed a rich set of alternative DBMS; such as - NoSQL, NewSQL. In this paper, we focus on different NOSQL databases, characteristics and their working in Big Data Analytics. This paper is intended to help users, especially to the organizations to obtain an independent understanding of the strengths and weaknesses of various NoSQL database approaches to supporting applications that process huge volumes of data for their projects and applications.
