The document presents on database management systems. It defines a database as a collection of programs that stores and extracts information. It then gives examples of database applications and discusses the steps in database design such as requirements analysis and conceptual modeling. Several functions of database management systems are outlined including data storage, security, and transaction management. The roles and benefits of DBMS are also summarized.

3. What is Database
• collection of programs that enables you to
store and extract information from a
database
• created to operate large quantities of
information by inputting, storing, retrieving,
and managing
M.A.J.U

4. Examples of Database
Applications
• computerized library systems
• automated teller machines
• flight reservation systems
• computerized parts inventory systems
M.A.J.U

5. STEPS IN DATABASE DESIGN
• Requirement analysis
− What does the user want?
• Conceptual database design
− Defining the entities and attributes, and
the relationships between these --> The
ER model

7. Functions of a Database Management
System
• several functions that a DBMS performs to
ensure data integrity and consistency of
data in the database
• Ten functions in the DBMS are:
− Data Dictionary Management
− Data Storage ManagementM.A.J.U

8. Functions of a Database Management
System
− Data Transformation and Presentation
− Security Management
− Multiuser Access Control
− Backup and Recovery Management
M.A.J.U

9. Functions of a Database Management
System
− Data Integrity Management
− Database Access Languages and
Application Interface
− Database Communication Interfaces
− Transaction ManagementM.A.J.U

10. Role of Database Management
System
• interaction between end-user and the
database
• create an environment in which end users
have better access to more data
• Database is stored as a collection of files
M.A.J.U

11. DBMS benefits
• Occupies minimum storage space
• No unnecessary data
• Easy to update
M.A.J.U

12. Data Management Task
• Data management task fall into one or four
general options
− Storage space
− Backup strategy
− Speed

13. Database Tables
• Creating database tables
− Name the field
− Specify the field type
− Specify the field size
M.A.J.U

14. Database Tables
• Entering data in tables
− After the tables has been set up, data
can be entered by
• Viewing records
• Sorting records
M.A.J.U

15. Querying a Database
• Allow the DBMS to locate records
• Establish relationship
• List a subset of records
• Perform calculations
M.A.J.U

16. Querying a Database
• Delete obsolete records
• Perform other data management task

17. Field Types of DBMS
• Text field
• Numeric field
• Time field
• Logical field
M.A.J.U

18. Field Types of DBMS
• Binary field
• Counter field
M.A.J.U

19. ORDBMS
• object-relational database management
systems.
• How DBMS accessed languages:
− directly using programming languages
M.A.J.U

20. RDBMS VS ORDBMS
• Stands for
–Relational database management
system
–Object-relational database management
systems
• Difference between RDBMS and
ORDBMS
–They are both database management
systems M.A.J.U

21. DB2 database management
• DB2 database management : that was
introduced by IBM in 1983.
• Editions of DB2 :
– DB2Workgroup
– DB2 Workgroup Unlimited
M.A.J.U

22. DB2 database management
–DB2 Enterprise Server Edition
–DB2 UDB Data Warehouse
Enterprise Edition (DWE)
• DB2 has APIs for many languages
including the following.
–Java
–C
