Database Management System (DBMS) refers to a set of computer programs in a
software package specifically designed for the creation, maintenance, and
use of databases by following appropriate security measures.
The database management system acts as an intermediate between the database
and the end-user or third-party software. It establishes a multi-user
environment allowing multiple users to create, access, or manipulate data in
the database in parallel.
In this article, we explain some real-time applications of DBMS. However,
they are not limited to just these applications or uses. There can be many
more applications/uses of DBMS in different fields for specific database
requirements.
What are the applications of DBMS?
Due to the significant advantages, the use of database management systems is
very common in various sectors, be it education, banking,
telecommunications, defense, industry, etc. We can also say that the
applications of the database management system are countless.
Following are some of the essential applications of DBMS in real life based
on various fields:
Railway Reservation System
DBMS plays an important role in the railway reservation system. It helps in
managing the database for storing customer data like name, mobile number,
booking status, departure and arrival stations, etc.
Similarly, data like arrival and departure times of trains, schedules,
seating arrangements for vacant seats, etc. is also stored in the database.
In any case, if trains are delayed or canceled, users are notified through
database updates.
Airline Reservation System
Like Railway Reservation System, Airline Reservation System also uses DBMS
to keep or maintain records of users and details of flights in the database.
Education
Online exams are quite common these days. Therefore, universities, colleges,
and examination boards take advantage of DBMS to keep or update data like
registration details of
students, fee payment, exam centers, exam results, etc. in the database.
Apart from examinations, schools and universities also maintain databases to
store the available courses, personal records of students, attendance,
grades or results, and many other details.
Library Management System
Libraries hold thousands of books and keeping records of books in physical
registers or copies can be very difficult. Hence, DBMS has become a part of
the library management system, which enables the management to maintain
book
records like availability, date of issue, book name, author name, book
issuer, book taker name, etc. in databases.
It is very easy to check or search specific book records from the database
using DBMS.
Banking
Banking is considered one of the primary applications of databases. Banks
have to maintain millions of user accounts and DBMS helps in keeping the
records of each user systematically. Additionally, other baking data like
day-to-day transactions, loans, fixed deposits, balance sheets, interest
credits,
ATM
records, etc., everything is maintained with the help of database management
systems.
Credit Card Transactions
Purchases made through credit card or credit card transaction details are
also maintained using DBMS. The database management system helps to keep the
information secure and also eases the creation of monthly or yearly
statements.
Social Media Sites
With the advent of smartphones, the use of social media sites has increased
a lot. Using these sites, people communicate with their friends, family, or
relatives from all over the world. Thousands to millions of accounts are
created daily on popular social media sites like Facebook, Twitter,
Pinterest, TikTok, etc.
All the records are stored and managed securely and systematically in
databases with the help of DBMS.
Industry
In the industry, there are many employees and their records are maintained
using database systems. Apart from this, inventory management in big
industries is also done with DBMS.
Manufacturing
Manufacturing companies manufacture a large number of related products on a
daily basis. They need to maintain a record of all the ins and outs of
products, quantities, purchases, payments, invoices, workers' data, etc. All
this is possible with DBMS which helps in maintaining or updating all the
required records in the database.
Telecom
The database is one of the essential requirements in the telecom sectors to
store the records of call details, network usage, subscriber information,
subscription package details, bill payments, etc. It is very difficult for
telecom companies to keep or maintain such huge data without DBMS.
Broadcast Communication
Broadcasting involves the distribution of audio and/or video signals to a
large number of users or subscribers. Generally, broadcast communication is
done for public users like
TV
(television), online streaming, internet-based media, etc.
Records of events, timings and schedules, and subscribers' details such as
personal information, payment status, subscription packages are all stored
in the database with the DBMS.
Accounting & Finance
These days, records related to accounting and finance are not stored in
physical registers, especially when big data is maintained. Instead, such
records are kept in the database using a DBMS, making it easily accessible.
Everything like sales, finance statements, purchase of financial assets,
purchase or sale of stocks or bonds, etc., are stored with the database
system.
Defense
Keeping records of soldiers has become very easy with the help of DBMS in
the defense sector. Apart from this, there are many files or confidential
data that need to be kept safe. DBMS helps to keep information secure. With
DBMS, it is also easy to search or find any specific information about any
soldier or other record.
Online Shopping
Online shopping or ordering has become popular these days. One can order
most of the items without wasting time from home using e-commerce sites.
DBMS helps in keeping records of purchase information, payment, invoice
bill, order status, etc. In addition, e-commerce sites and other online
platforms take advantage of DBMS to store customer data, maintain stock,
prices, etc.
Sales & Marketing
Database systems also help manage sales and marketing data. For example,
customer information, dealer information, list of products, items bought and
sold, invoices, etc.
Human Resource Management
Big firms and multinational companies hire many employees to get their work
done. Human Resource Management keeps and manages the records like name,
designation, timetable, salary, tax, etc., of the employees. DBMS helps to
manage all such information in databases securely.
Medical
In medical, DBMS helps in keeping the record of medicines and updating the
list accordingly. Additionally, other details such as patient records,
appointments, payments, invoices, doctor schedules, and other information
are also stored or managed in databases in real-time using DBMS.
Agriculture
In the agriculture sector, DBMS helps in keeping records of crops,
fertilizers, machinery, and livestock within the database. The buy rate,
sell rate, cash usage, etc., can also be updated in the database.
Summary
This article discusses more than 15 applications or uses of database
management systems in real life. With each new technology arriving in the
current computational era, it will have more and more uses in the days to
come. The database management system has made it very easy to keep or update
day-to-day records in different fields/ sectors.
