Explanation:
A database consists of several components. Each component plays an important role in the database system environment.
The major components of the database are as follows::
Data :: It is raw numbers, characters or facts represented by value. Most of the organizations generate, store and process a large amount of data. The data acts as a bridge between the hardware and the software. Data may be of different types such as User data, Metadata and Application Metadata.
Software :: It is a set of programs that lies between the stored data and the users of the database. It is used to control and manage the overall computerized database. It uses different types of software such as MySQL, Oracle etc.
Hardware:: It is the physical aspect of the computer, telecommunication, and database, which consists of the secondary storage devices such as magnetic disks, optical discs etc., on which data is stored.
Users:: It is the person, who needs information from the database to carry out its primary business responsibilities. The various types of users which can access the database system are as follows:
Database Administrator (DBA) :: A person, who is responsible for managing or establishing policies for the maintenance and handling of the overall database management system is called DBA.
Application Programmers ::The people, who write application programs in programming languages to interact and manipulate the database are called application programmers.
End-user:: A person, who interacts with the database system to perform different operations on the database by inserting, deleting etc.
