Database often abbreviated DB, is basically a collection of
information organized in such a way that a computer program can quickly select
desired pieces of data. A database can be referred to as an electronic filing
system. A database is an
organized collection of data. It is the collection of schemas, tables, queries,
reports, views and other objects. The data are typically organized to model
aspects of reality in a way that supports processes requiring information. A
database is a collection of information that is organized so that it can easily
be accessed, managed, and updated.

An
alternative concept in database design is known as Hypertext. In a Hypertext database, any object,
whether it be a piece of text, a picture, or a film, can be linked to any other
object. Hypertext databases are particularly useful for organizing large
amounts of disparate information, but they are not designed for numerical
analysis. Traditional databases are organized by fields, records, and files. A field is a single piece of information; a
record is one complete set of fields; and a file is a collection of records.
For example, a telephone book is analogous to a file. It contains a list of
records, each of which consists of three fields: name, address, and telephone
number.

To
access information from a database, you need a database management
system (DBMS). This is a
collection of programs that enables you to enter, organize, and select data in
a database. Increasingly, the term database is used as shorthand for database
management system. There are many different types of DBMSs, ranging
from small systems that run on personal computers to huge systems that run on mainframes.
