Database Users
Database administrators – DBA is responsible
for authorizing access to the database, for coordinating and monitoring its
use, and acquiring software and hardware resources as needed.
Database designers – identify data to be stored
in the database and choosing appropriate structures to represent and store the
data. Most of these functions are done
before the database is implemented and populated with the data. It is the responsibility of the database
designers to communicate with all prospective users to understand their
requirements and come up with a design that meets these requirements. Database designers interact with all
potential users and develop views of the database that meet the data and
processing requirements of these groups.
The final database must support the requirements of all user groups.
End Users
Casual End Users – occasionally access, may
need different information each time.
Use query language to specify requests.
Naive or parametric end users – main job is to
query and update the database using standard queries and updates. These canned transactions have been carefully
programmed and tested.
Sophisticated end users – engineers,
scientists, analysts who implement applications to meet their requirements.
Stand alone users
Stand alone users – maintain personal databases
using ready made packages.
