# What is the difference between RDBMS and DBMS?

**Full form of** DBMS: Database management system

**Full form of RDBMS****:** Relational database management system

Basically, RDBMS is the extension of DBMS.

In DBMS data is stored in a file or we can say that a hierarchical form or a navigational form, whereas in RDBMS data is stored in Tabular form.

The DBMS does not support distributed database, Normalization etc. whereas RDBMS support.

In RDBMS there is a concept of primary key, foreign key etc. but there is no such constraint in DBMS.

**Example of DBMS is XML or any file system.**

Example of RDBMS is Postgre, SQL Server, oracle etc.
