Topics : DBMS & RDBMS

By : Mr. Jitendra Thakur

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.

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

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

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.

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……

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.

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.

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

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
