1.DBMS (Data base management system ) is a process of managing data for efficient retrieval and storage of data.
2.The data base which is used by relations( tables) to acquire information retrieval are known as RDBMS. example- sql DBMS is the Database Engine itself like MySql Server
RDBMS is a DBMS that is based on the relational model. Almost all modern DBMS's are RDBMS's. Older DBMS's were based on different models (network, hierarchical, etc.) Both DBMS and RDBMS are management system, used to manage database. Basic difference between them is that in case of RDBMS we can create permanent relationship between tables on the basis of primary key and foreign key and it satifies all the codd rules.
