Relational database

A relational database (RDB) is a database based on the relational model of data, as proposed by E. F. Codd in 1970.

A Relational Database Management System (RDBMS) is a type of database management system that stores data in a structured format using rows and columns.

Many relational database systems are equipped with the option of using SQL (Structured Query Language) for querying and updating the database.
