Question: Difference between DBMS & RDBMS?

Answer: ***Source: wiki.answers.com***

DBMS stands for Database Management System which is a general term for a set of software dedicated to controlling the storage of data.

RDMBS stand for Relational DataBase Management System. This is the most common form of DBMS. Invented by E.F. Codd, the only way to view the data is as a set of tables. Because there can be relationships between the tables, people often assume that is what the word "relational" means. Not so. Codd was a mathematician and the word "relational" is a mathematical term from the science of set theory. It means, roughly, "based on tables".

DBMS:1)In dbms no relationship concept
2)It supports Single User only
3)It treats Data as Files internally
4)It supports 3 rules of E.F.CODD out off 12 rules
5)It requires low Software and Hardware Requirements.
6)FoxPro, IMS are Examples

RDBMS:
1)It is used to establish the relationship concept between two database objects, i.e, tables
2)It supports multiple users
3)It treats data as Tables internally
4)It supports minimum 6 rules of E.F.CODD
5)It requires High software and hardware requirements.
6)SQL-Server, Oracle are examples Source: CoolInterview.com

DBMS : Data Base Management System
..... for storage of data and efficient retrieval of data.
Eg: Foxpro

1)A DBMS has to be persistent (it should be accessible when
the program created the data donot exist or even the
application that created the data restarted).
2) DBMS has to provide some uniform methods independent of a
specific application for accessing the information that is
stored.
3)DBMS does not impose any constraints or security with
regard to data manipulation. It is user or the programmer
responsibility to ensure the ACID PROPERTY of the database
4)In DBMS Normalization process will not be present

RDBMS: Relational Data Base Management System
.....the database which is used by relations(tables) to
acquire information retrieval
Eg: oracle, SQL..,

1)RDBMS is based on relational model, in which data is
represented in the form of relations, with enforced
relationships between the tables.
2)RDBMS defines the integrity constraint for the purpose of
holding ACID PROPERTY.
3)In RDBMS, normalization process will be present to check
the database table cosistency
4)RDBMS helps in recovery of the database in case of loss of
database due to system failure or any other reason
