What is a Database?
A database is a collection of data used to store and manage different types of information. For instance, consider an online shopping application. A database can be used to store user credentials, user addresses, order history, payment details, product details, stock details, and more. The database allows for easy organization and retrieval of data, making it an essential part of modern applications.
Why were databases created?
Databases became popular in the 80s and 90s with the rise of data. Companies like Google and Facebook generate massive amounts of data that need to be stored. This data is useful in various computer science fields, which is why databases were created as a means of storing and accessing it.
Understanding DBMS
DBMS stands for Database Management System which is responsible for managing databases. Its primary function is to efficiently store and retrieve data from the database. The aim is to manage the database effectively, enabling users to retrieve data easily and store data efficiently.
The Importance of Database Management Systems
In the past, data was stored in CSV files, but this is not suitable for large amounts of data. Retrieving and updating data from these files is a challenging task, requiring significant optimization. Database Management Systems (DBMS) were created to solve this problem. DBMS software is responsible for efficiently storing and retrieving data from a database. Although data is stored on drives, DBMS software manages how data is stored and accessed. When data needs to be accessed, it can be requested from the DBMS software. DBMS acts as a data manager, which can be accessed by human beings or software.
Types of Database Management Systems
In the past, Relational Databases were commonly used where tables were used to store data. Multiple tables had relations to avoid redundancy of data. SQL was used to support Relational Databases.
These days, Non-Relational Databases are more popular as they store data in various formats, not just tabular. Examples of languages supported by non-relational databases include MongoDB, Firebase, Amazon DynamoDB, Cassandra, and HBase.
Top Applications of DBMS
DBMS is used in various industries, from gaming to e-commerce. Here are some common applications of DBMS in real life.
Online Shopping
Online shopping has become a common way of buying products. To make a purchase, customers create an account on e-commerce websites like Amazon or Flipkart and provide their personal information, including name, phone number, email, and address. These e-commerce companies keep track of their customers’ orders and personal data, while also storing information about their products, sales, and purchases. Database management software is utilized to store all of this data. The back-end of online shopping applications uses both a database and database management system software to provide customer services.
Reservation System
In many places such as movie theaters, train and airline tickets, we reserve seats and provide our details to reserve a specific seat. Reservation systems use databases and management systems for this purpose. Data stores include customer name, train number, price, and date. These details are essential to identify the correct person during the trip.
Importance of Databases and DBMS for Telephone Companies
Telephone companies heavily rely on databases and database management systems (DBMS) to function. With sim cards being a common medium for calling and internet access, it’s important for mobile operator companies to keep track of daily data limits and calls made. They utilize database management software and databases to store user data, which is later used to generate bills according to usage. This reliance on DBMS also extends to internet service providers and other related industries.
Manufacturing Companies and DBMS
In the US, manufacturing companies rely on databases and management systems to keep track of their products. They produce large numbers of items every day, which are sold to various companies. This is where a reliable DBMS comes in handy to efficiently manage this information.
Military Information in DBMS
Military information is highly sensitive and confidential data for every country. Governments use DBMS to store and secure this data, which includes soldier details, operations, locations, and more.
HUMAN RESOURCES MANAGEMENT
In every major company, there’s a Human Resources team responsible for managing employee-related matters such as salaries, benefits, leaves, and taxation. To make things easier, they use a Database Management System extensively for maintenance.
Management of Student Data in Universities and Colleges Using Databases
In US universities and colleges, maintaining student data, course enrollment, professors handling particular subjects, departments, and colleges can be challenging. However, databases have made it easier to manage these records. The database management system helps with keeping track of all the details.
BANKING
A database management system is the heart of banking operations. It stores customer information such as account balances, transactions, and loans, as well as bank operation details.
In the past, banks used registers and ledgers to maintain records, limiting customers to withdrawing money from the same branch. However, databases have made it easier to manage these tasks and given customers global access to their funds.
Income Tax Department
Each individual is assigned a unique identification number which the Income Tax Department uses to keep track of their income, tax payments, credit score, and other related details. The department centrally manages all this information by connecting it with the individual’s bank records through a database. Database Management Systems are used for effectively maintaining and organizing all these records.
Library Management System
In a library, books are provided to customers for reading and then returned. It is necessary to keep track of which customer has borrowed which book, the due date for returning the book, and any associated charges. This is all efficiently managed using databases.
Social Media and Database Management
Most of us have Facebook, Instagram, LinkedIn, or other social media accounts, but have you ever considered the mechanics of logging in and viewing posts? Or how friends are linked to our account? These functions rely on a database management system, which saves and processes the data that powers social media operations.
Mobile Games and Database Management
Online mobile games store our progress, characters, coins, and levels through database management systems, allowing us to retrieve this data quickly with low latency.
Mobile Applications and Databases
Mobile applications, such as Contacts, use small databases to store contact names and numbers. Core mobile operations, like user accounts, settings, and passwords, also rely on database management systems to store data.
Importance of Database Management System
Every digital device that stores any form of data uses a database. In today’s world, where data is crucial, a database management system is paramount for managing this information. It has real-world applications in various industries, including healthcare, finance, education, and more. Large technology companies such as Google and Amazon rely heavily on DBMS to store and organize their data efficiently.
