Abstract: NoSQL databases were built in the need to deal with the increasing amount of complex data (Big Data), required in real-time web applications, and are mostly addressing some of these points: the focus on availability over consistency, horizontally scalable, distributed architecture, and open-source. The purpose of this paper is to present the reasons for a transition from RDBMS to NoSQL databases, to describe the main characteristics of non-relational databases and to compare and analyze three popular NoSQL solutions - Cassandra, MongoDB and CouchBase, outlining the results obtained during performance comparison tests. Each solution is optimized for different workloads and different use cases. Therefore, each has its own strong points and weaknesses.
