3. DBMS -: A Database management system (DBMS) is system software f
or creating and managing database .
A DBMS makes it possible for end users to create , protect , read , upda
te and delete data in a database .
DBMS Function
Store data updates data
Retrieves data
Summary -: DBMS is designed to store and manage database .
. 1960 - First DBMS designed by Charles Bachman at GE. Integrated
Data Source (IBS) .

4. Database management system were developed to handle the following
difficulties of typical file-processing systems supported by conventional
Operating systems .
Data rebundancy and inconsistency
Difficulties in accessing data
Data isolation – multiple files and formats
Integrity problems
Atomicity of updates
Concurrent access by multiple users
Security problems
PURPOSE OF DATABASE SYSTEM

5. COMPONENT OF DBMS
SOFTWARE
DATA
PROCEDURE
HARDWARE USER

6. Keys In DBMS
Candidate key
Primary key
Super key Foreign key
Composite key
Compound key

7. 1. REDUCING DATA REBUNDANCY
2. SHARING OF DATA
3. DATA INTEGRITY
4. DATA SECURITY
5. PRIVACY
6. BACKUP AND RECOVERY
7. DATA CONSISTENCY
ADVANTAGES OF DBMS

8. 1. COMPLEXITY
2. SIZE
3. COSTS OF DBMS
4. ADDITIONAL HARDWARE COSTS
5. COST OF CONVERSION
6. PERFORMANCE
7. HIGHER IMPACT OF A FAILURE
DIS-ADVANTAGES OF DBMS

9. Performance and tunning
. Tuning SQL statements at runtime – automatically
. Support mixed workloads – OLTP/DW or BI seamlessly .
Backup and recovery
. Track backups and recover databases – automatically
Upgrades and patch deployments
. Seamless and integrated – no downtime
Other administration tasks
. Self – securing , self – handling , and continuous DB a
availability
. Tighter integration of structured and unstructured data
Future : DBMS automation a top focus for
most leading DBMS provide…..
