RDBMS (Relational Database Management System)

An RDBMS (Relational Database Management System) is a DBMS that stores data in tables made of rows and columns, and links tables through keys. Data is queried and changed with SQL.

Relationships are expressed with primary keys (unique row identifiers) and foreign keys (references to rows in other tables). An RDBMS enforces rules such as data types, uniqueness and referential integrity, and supports ACID transactions. MySQL, PostgreSQL, Oracle, SQL Server and SQLite are relational databases.
