Hi Shital !

what is the difference between DBMS & RDBMS ?

The "R" stands for "Relational" ("DBMS" = "Data Base Management System", of course), for some databases are not relational (hierarchical for example), especially some legacy ones.

Best regards.

There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors

Mainstream databases such as Oracle, DB2, MySQL, PostgreSQL, etc. are relational databases.

Other, non-relational databases include object-oriented databases such as db4o, Ozone and Versant Object Database.

An example of a hierarchical database would be Adabas.
