DBMS vs. RDBMS:
1. DBMS includes how data stored in table but RDBMS includes
sql syntax for relating tables with another.
2. DBMS does not show relation but RDBMS shows relation.
3. In DBMS all the tables are treated as different entities
but the tables in RDBMS are dependant and uses established
various integrity constraints on these tables.
4. In DBMS only one user can access the same database at a
time but in RDBMS many users can simultaneously access the
same database.
5. In both DBMS & RDBMS the data is stored in the form of
rows and columns. But the main difference between the DBMS
and RDBMS is we can establish the relation between the
tables in RDBMS. In case of DBMS we cannot establish
relation between tables.
6. In DBMS duplication of rows ans columns. But in RDBMS
there is no duplication of rows and columns.
7. In DBMS rows and columns are independent. But in RDBMS
rows and columns are dependent.
8. DBMS is for single user only. RDBMS is for multi-user.
9. DBMS does not support client server architecture. RDBMS
supports client server architecture.
10. DBMS there is no tight security of database. RDBMS ther
are multiple level of security.
11. In RDBMS the normalization is there while in DBMS no
such normalization is there.
12. eg: RDBMS-->oracle,sql server,MY SQL,DB2(IBM),
DBMS-->sysbase foxpro
