Database Essay

1491 words - 6 pages

Database A database is an organised body of related files and or information.
It is simply an automated library system an is maintained as an
integral part of most organisations worldwide. A cite on the World
Wide Web, the Webopedia Computer Dictionary, refers to the database as
a collection of information organized and presented to serve a
specific purpose. (A telephone book is a common database.) A
computerized database is an updated, organized file of machine
readable information that is rapidly searched and retrieved by
computer.

A Data Base Management System is a collection of programs that enables
you to store, modify, and extract information from a database. There
are many different types of DBMSs, ranging from small systems that run
on personal computers to huge systems that run on mainframes. The
following are examples of database applications:

· computerized library systems

· automated teller machines

· flight reservation systems

· computerized parts inventory systems

From a technical standpoint, DBMSs can differ widely. The terms
relational, network, flat, and hierarchical all refer to the way a
DBMS organizes information internally. The internal organization can
affect how quickly and flexibly you can extract information. Requests
for information from a database are made in the form of a query, which
is a stylized question. For example, the query :

SELECT ALL WHERE NAME = "SMITH" AND AGE> 35

requests all records in which the NAME field is SMITH and the AGE
field is greater than 35. The set of rules for constructing queries is
known as a query language. Different DBMSs support different query
languages, although there is a semi-standardized query language called
SQL (structured query language). Sophisticated languages for managing
database systems are called fourth-generation languages, or 4GLs for
short.

The information from a database can be presented in a variety of
formats. Most DBMSs include a report writer program that enables you
to output data in the form of a report. Many DBMSs also include a
graphics component that enables you to output information in the form
of graphs and charts.

Migrating from the manual and paper file set up is always an advantage
in its own capacity. We shall highlight the major advantages of using
a database or Data Base Management System in an organisation. Using a
database will reduce both data redundancy and inconsistency. For
larger or even smaller organisations like a small time starting estate
agency, a database will promote sharing of data for example when
referring to client files. Their rent or sales teams can share the
information in order to be able to assist their clients better.
