What is NoSql DB

NoSQL Databases

* A NoSQL database (sometimes called as Not Only SQL) is a database that provides a mechanism to store and retrieve data other than the tabular relations used in relational databases.

* These databases are schema-free, support easy replication, have simple API, eventually consistent, and can handle huge amounts of data (big data).

* The primary objective of a NoSQL database is to have the following −

1. Simplicity of design,
2.Horizontal scaling, and
3.Finer control over availability.
