This document discusses database management systems (DBMS) and relational database management systems (RDBMS). It defines data and databases, lists examples of DBMS like Oracle and SQL Server, and describes the components, applications, advantages, and disadvantages of DBMS. It then defines RDBMS as a DBMS based on the relational model introduced by Dr. E.F. Codd. Codd developed 12 rules for RDBMS and the document lists some key differences between DBMS and RDBMS, including how relationships are defined and security features.

2. DBMS is a software system that allow us to
manage the data base.
DATA:- A data is Raw martial, fact, figure that give
the meaningful information i.e. require foe some
form of processing.

3. DATA BASE:- It is a group of information or A
collection of data may be organized in the form of
files or tables.
Examples:-
1. Oracle 9i, 10G, 10Gi, 11G, 11Gi
2. SQL-server-2005, 2010
3. DB2,Sybase,forpro, Ms-access2003,
2007, 2010,
Application DBMS O.S. Data Base

4. Components of DBMS:- 1. User
2. Hardware
3. Software
4. Data
Application of DBMS:- 1. Banking Sector
2. Universities
3. Railway Reservation
4. Finance
5. Sales

5. Advantages of DBMS:-
1.Reduce the redundancy from Database.
2. Sharing of data.
3. Important in data security.
4. Better interaction with user.
Disadvantages of DBMS:-
1. Cost of Software.
2. Cost of Hardware.
3. Complexity of back-up of recovery.

6. RDBMS:- RDBMS is a DBMS i.e.
based on Relational model as introduce
by Dr. E.F. codd…..
Codd’s role for RDBMS:- Dr.
Codd is an IBM researcher who
developed relational data base in
1970…..
In 1905 Codd published 12 rules……

7. 1)-The Information rule.
2)-Granted access rule.
3)-Systemic treatment of NULL
values.
4)-Dynamic online Catalog based on
relational model.
5)-Comprehensive data sub-language
rule.
6)-View updating rule.

8. 7)-High level Insert , Update, Delete rule.
8)-Physical data Independence.
9)- Logical data Independence.
10)- Integrity data Independence.
11)- Distribution data Independence.
12)- Non-subversions rule.

9. DBMS RDBMS
1. In DBMS relationship
between two table or file
are maintained
programmatically.
2. DBMS does not support
client-server
architecture.
3. DBMS does not support
distributed.
4. No security.
1. In RDBMS relationship
between two table or file
can be specified at the
time of table creation.
2. RDBMS supports client-server
architecture.
3. RDBMS supports
distributed.
4. Multiple level of security
a) Log in at O.S. level
b) Commend level
c) Object level

10. 5. DBMS may satisfy
less then 7 or 8 rules
of Dr. E.F. codd
5. More then 7 or 8
rules of Dr. E.F. codd
