In the cyber world, everything is data. Text, videos, audios, images, and various types of documents are all just different types of data. So, data is everything that’s useful or can be processed to generate some information. Because the traditional file system isn’t enough to store data nowadays, databases have become the primary method for storing data.

Introduction

A database is an organized collection of data on which we can perform basic operations like creating, retrieving, updating, and deleting. These simple operations are known as CRUD operations. For example, Educative has a database to store and manipulate data. This same database is used to view data related to courses, users, subscribers, payments, and a lot more.

MongoDB is an open-source, document-oriented database that’s categorized under NoSQL databases because its data storage process doesn’t rely on tables. Instead, it stores data in the form of document collections. The basic data storage unit in NoSQL databases like MongoDB is the document. Each document consists of a set of key-value pairs. A set of documents associated with a set of functions is called a collection.
