What is the difference between SQL and NoSQL?

1. Whereas SQL databases are relational, hence the name relational database management system (RDBMS), NoSQL database is non-relational or distributed. SQL databases are table-based whereas NoSQL databases are document-based, graph databases, wide-column stores, or key-value pairs.
