MongoDB Basics
Learn the basics of one of the most popular NoSQL databases.
We'll cover the following...
Imagine we’re building a new shopping feature for our OnlineStore platform where customers can bookmark favourite products and track items they’ve viewed.
In a traditional relational database, we’d need to create new tables, define strict schemas, and maintain relationships. But what if we wanted to move fast, store customer behaviour data flexibly, and scale to millions of users?
This is where MongoDB, a document-based NoSQL database, comes in. In this lesson, we’ll explore the basics of MongoDB and understand how it helps developers work with flexible data models.
By the end of this lesson, we’ll be able to:
Understand MongoDB’s core structure (documents and collections).
Perform basic CRUD operations.
See how indexing works in MongoDB.

To begin, let’s explore why a database like MongoDB plays such an important role in modern application development.
In our online store example, we saw that data doesn’t always fit neatly into rows and columns. Modern applications need to handle diverse, evolving data structures that change rapidly over time. MongoDB was designed to address this challenge by providing a flexible way to store and query data, making it easier for developers to build, scale, and adapt applications quickly.
It’s a popular open-source NoSQL database that falls under the category of document-oriented databases.
Unlike traditional SQL databases, which store data in tables with predefined schemas, MongoDB ...
