IS Ms Access DBMS or RDBMS? I also do Google to find answer of this question,but in some website or blog says it is DBMS while others are says it is RDBMS.. so what is correct answer? and Please understand why it is DBMS or RDBMS?
MS Access is a Relational Database Management System so therefore RDBMS, however you can use it in a non-relational fashion if you so wish so it can be used as a DBMS.
Short Answer: Both.
Detail:
Microsoft Access is a DBMS but also something more: a personal database system. That is, a DBMS plus an application generator. While Microsoft Access contains a DBMS engine that creates, processes, and administers the database, it also contains form, report, and query components that are the Microsoft Access application generator.

Microsoft Access is an application development tool, not a DBMS or an RDBMS.
The Access application is bundled with (but distinct from) Jet/ACE, which is a system for sharing data over a filesystem or via ODBC. In principle that can include accessing relational or non-relational databases. Jet/ACE isn't "relational" though. It is based (very loosely) on the SQL model of data rather than the relational model but is more of an ISAM cursor-engine than any SQL DBMS.
