The document discusses different roles involved in database management. It describes people on the scene like the Database Administrator who manages the database, Data Administrator who oversees information resources, and System Administrator who installs the DBMS. End users access the database without managing it. Behind the scenes are DBMS designers who create the complex software and Application Programmers who design DBMS integration with other software.

 For Small database one person
typically define, construct and
manipulates the database and there is
no sharing.

 The most important person in the
environment of Database is Database
administrator (DBA).

12. How many DBA’s?
 The number of DBA’s in an organization
depends upon the Following things

◦ Variety of DBMS:
◦ Experience of DBA/users:

13. Data Administrator:
 The need of data administrator arises
in a very large organization where
many databases may exist.

or applications of an organization.

 Larger organization also have system
administrator to manage the whole system.

 The main task of System administrator is to
installing the DBMS and its use with the
other software.

17. End Users:
 End users are the people who uses the
databases and are not responsible for
its management.

18. Casual Users:
 They have occasionally access to the
database and they may need different
information every time.

19. Native Users.

database regularly and know every
thing about the database.
 They regularly read, insert, delete and
update data in database.

use the database but they are very
important people in the environment of
database.

 DBMS is a complex software and it is very
difficult to design the DBMS and its
operation.

22. Application Programmer:
 They are professional programmers
who built DBMS with computer
language/programming.
