NoSQL, which stand for "not only SQL," is a database that provides a mechanism for storage and retrieval of data. It can accommodate a wide variety of data models, including document, graph stores such as Giraph and Neo4J, key-value like Redis and Riak, and wide-column. NoSQL is an alternative to relational databases or where data is modeled in tabular format.

 

NoSQL databases have become a preferred approach for a variety of reasons. Aside from its flexibility, its advantage also lies on its high scalability. NoSQL can handle huge amount of data since it supports automatic database partitioning, compared to SQL databases which need complex arrangements for sharding to be possible. It is also the preferred type for application that require multi-row transactions since SQL is table-based. NoSQL is also used when data is changing and growing over time and lacks structure.
