Using examples differentiate between a DBMS, RDBMS and a Distributed database

DBMS - Its a software package combination of various computer programs which can be used to control, administer, maintain and use of the database.

RDBMS - Its a database management system (DBMS) based on relational model introduced by E. F. Codd. Most of them databases like Oracle, SQl Server and DB2 are relational database model. DBMS stores the data, but in RDBMS stored the data based on the Codd Rules maintaining the database integrity.

Distributed database In a situation, you are using many computers for storing the data or database to spread the load across. This can also be referred as clustered solution. Data may be stored in multiple computers on the network which can distribute the load. Database replication improves database performance.

DBMS is a when data are not stored in table and RDBMS is used to all data are stored in table and distributed database when more than one table are connected with each other so its is called a distributed database
