NoSQL databases refer to the group of databases that are not based on the relational database model. Relational databases such as Oracle database, MySQL database, and DB2 database store data in tables, which have relations between them and make use of SQL (Structured Query Language) to access and query the tables. NoSQL databases, in contrast, make use of a storage and query mechanism that is predominantly based on a non-relational, non-SQL data model.
