First of all, a question arises what actually is a database management system?

“A database management system (DBMS) is a software tool that makes it possible to organize data in a database.”

In today’s lecture/ lesson we are going to briefly discuss the purpose and primary functions of a database management system.

The standard abbreviation for a database management system is DBMS. The ultimate purpose of a DBMS is to store and transform data into information to support making decisions. Business systems make everything easy for you and in a controlled manner.

What actually does a DBMS consist of? A DBMS consists of 3 basic elements described below.

#1 Physical Database:

It consists of the collection of files that contain the data.

#2 Database Engine:

It is software that enables us to access our content in the database and do modifications/changes to it.

#3 Database Scheme:

It tells us about the specification of the logical structure of the data stored in the database.

Let us explain DBMS through some common examples.

If there was no DBMS in the organization then what would the data look like? For a moment, consider yourself as the organization and all the data are the files on your computer. If you are a typical computer user then your data would be properly organized in their respective folders.

Presently consider the difficulties you are confronted with. Have you ever lost a document? Have you experienced issues finding a document? Probably yes. Maybe you are using various PCs and your documents are situated in various physical areas. Also, when was the backup of all your files the last time created? You do a backup, isn’t that so?

Presently consider an organization with 1k employees, each with their own particular PC. Could you see a portion of the difficulties when utilizing a File System?

Do you truly need basic monetary information floating around the workplace as simple documents on individual PCs?

Primary Functions of DBMS:

So what actually are the primary functions of a DBMS? It sorts out your documents in such a way that you have more control over your data.

A DBMS makes it workable for clients/users to make, alter, and update/modify information in database records. Once made, the DBMS makes it conceivable to store and recover information from those database records.

To be more specific, DBMS’s primary functions are

#1 Concurrency:

Multiple users can access the same database at the same time.

#2 Security:

Security rules to determine the access rights of users.

#3 Backup and recovery:

Procedures to Back up the information frequently and retrieve information if an issue happens. You can continue reading this to learn more about the best software to use to safeguard your data.

#4 Integrity:

Database structure and principles enhance the integrity of the information.

#5 Data descriptions:

A data dictionary provides a description of the data.

Inside an association, the improvement of the database is regularly controlled by database administrators (DBAs) and different authorities. This guarantees the database structure is effective and dependable.

The security aspects and control access are also controlled by Database administrators. Agency systems make sure that you have no problems in your business and that you can work without worries. For example, every individual inside an association utilizes the database in various ways.

Some of the employees may basically need to see the information and perform fundamental analysis. While some other employees are effectively required in adding information to the database or updating existing information.

This implies the database administrator needs to set the client’s consent. You don’t need somebody who just needs to see the database to erase parts of the database accidentally.
