Components of DBMS

Components of DBMS are essentials parts of Database Management System.

As we know that a Database Management System is a collection of data as well as instructions or set of programs required to manage the data.

DBMS is also a computerized record keeping system. A Database System manages, organizes and maintains the data so that the data can be provided to the user when required.

Today in This tutorial we will explain different components of operating system.

Why DBMS is Important ?

Database Management System or DBMS is important because of the following benefits.

DBMS is used in various organizations as an interface that helps the users in forming the connection in database.
DBMS helps in organizing the data in a way that data can be access easily.
DBMS can store, organize and monitor the big or large amount of data just by using a software.
DBMS is also helpful in sharing the data among the organizations.

What are the components of DBMS ?

This questions is generally asked in Technical Interview.

Essential components of DBMS are as follow –

Data
Hardware
Software
Users

We have explained these different components of DBMS here in this tutorial one by one.

1. Data

Data is one of the most important components of DBMS in a Database Management System. Data is a collection of facts and statistics which are stored in the database.

The computer performs operations on the data is stored and can be transmitted in the form of electrical signals.

The main purpose of database system is to store, process and manage data according to user requirement.

The data may be in the form of text, sound or image data is stored in the database.

2. Hardware

Since Database management system is a computerized system and in a computerized system hardware is essential component.

The physical components of a computer that can be touched are called hardware.

The hardware is used to perform different tasks such as taking input or output, for storage and for processing etc.

Some important hardware components can be listed as follows-

(i) I/O devices such as keyboard, mouse, monitors, printers, camera etc.

(ii) Secondary storage devices such as CD-R/RW, DVD, Blu-ray drive, hard drives, SD card etc.

(iii) Processors such as CPU.

( iv ) Main memory such as RAM, ROM etc.

These are some hardware components which are involved in a database management system and without these components a database system environment is not complete.

3. Software

Software is another essential components of DBMS.

Software is a collection of programs or set of instructions used by computer within a database system to maintain the data or process and manage the data.

The most important software is DBMS itself. It uses three types of software to enable the database system work properly. Those three are listed and explained below-

(i) Operating system software: Operating System software control and manages all hardware components. It also enables processing of all other software in the computer properly. For example Windows, Linux, MacOS etc.

(ii) DBMS software: DBMS works as a controller in the database system. It controls, processes and maintains the data in a proper way. For example ORACLE, firebird, SQL Server, PostgreSQL etc.

Application Programs and Utilities: Application programs are the layout with which the user can have understanding of database access to the database and the application programs along with the DBMS software enables the user interaction with the data in the database. For example Python, C, C#, R etc.

Utilities are some programs which are used to improve the performance of the database.

4. Personnel Or Users

Personnel are the people components of DBMS. Personnel are the users who actually use and interact with DBMS.

Different types of personnel are as follows-

Database Administrators: They manage and monitor the use and functioning of the DBMS. They are responsible for the whole database system and authorize access to the database.

Application Programmers: They write the application programs through which the user can have access to the database.

End Users: They are the people who use application programs to perform different tasks on the database.
