Different Types of database users
A main objective of a database system is to provide a domain
for regain information from the databases and storing new information into the
database by the users. Basically database have mainly four types of different
database users that use it according to their needs, sorting by the behavior
that they are suppose to interact with the organization.
Application programmers:
These are the experts who interface with the organization
through the use of DML (Data manipulation Language) calls, that are coded in a
program written in a host language (for example, COBOL, PL/S, Pascal, C). These
languages are the basically mentions to as application programs
E.g.: Government, banks, Business professionals, website
owners, Mails, and Companies. These all uses applications that Transfers data,
useful information and money.
Sophisticated Users:
These are the users who use these systems directly. They are
not programmers and they don’t have knowledge of programs basically. These
entire queries are submitted to a system who converts it into useful
information. These users send request in database query to retrieve the
information they needed to implement
Specialized Users:
These are those who
are specialized in professional database applications like animated and
graphics databases. They are used for banking, accounts and in personal
computers.
E.g.: modern system like mobiles, tabs, laptops that uses graphic
design in video and audio.
Naive users:
these are the common peoples or persons that
use database applications for their personal and business uses. These applications
make a work easy for owners, managers and workers.
For example: When a person buys something and pay a bill via
credit cards then a data is updated in account. That’s how it works.
A user updates database over time to time and the
information is deleted and inserted according to needs. The overall information
that is stored in database at a particular time is known as instance of the database.
The layout and template design is called the database schema.
