what is the main difference between Dbms and Rdbms?
i am very confused. can anyone help me out?

DBMS = Database Management System
RDBMS = Relational DBMS

That is, the RDBMS set is a true subset of the DBMS set, which also includes
hierarchical, networked(?) and object-oriented databases. The former two
are legacy products, and the latter group never really took off. In
practice, when someone says DBMS, I would assume that he means RDBMS unless
he explicitly say something else. Relational DBMS completely dominate the
market today.
