Difference between DBMS and RDBMS--
DBMS i.e. DataBase Management System is a collection of
Data in a file which is not organised and related in any
case..Its just a file in which resords has been inserted
for further uses and that caould be any format...As compare
to it RDBMS is a DBMS that is related and organised
collection of data..By organised we mean that it is in a
particular and in pre defined format and relational means
that each data is related to each other in some order.
RDBMS supports tables..A Table is a something which has
Rows and Columns.Table contains Field and Fields contains
Records.Row of Table is also called "TUPLES" sometimes and
columns are called Attributes..
RDBMS also supports relationship between 2 tables i.e.
PRIMARY and FOREIGN key relationship..
RDBMS also provide DML,DDL and DCL for entering data and
manipulating it at column and table level...
RDBMS also supports CHECK constraints before entering any
data in the table and it also provides validations like NOT
NULL and UNIQUENESS....
SQL has been written to support RDBMS and it dos not
support DBMS...
RDBMS supports multiple users to access the same data at
the same time but DBMS supports single user to allow
accessing the data at a particular point of time...
There is one more concept of Codd's Rules..Professor
E.F.Codd has given its 12 rules..Hence any DBMS that
supports these Codd's rules becomes an RDBMS..
RDBMS also supports Data Normailization while a DBMS not.
There is one for fact that no RDBMS supports and follows
all 12 Codd Rules...
DBMS does not supports Client/Server Architechture while
most of the RDBMS supports Client/Server Architechture...
DBMS does not support Distributed databases but most of the
RDBMS supports...
RDBMS examples-Oracle,My SQL,SQl Server,MS-Access,Sybase,
Ingrase etc.
DBMS examples-Visual Foxpro etc.
