INTRODUCTION
MongoDB is one of the most popular NoSQL databases, widely used for its flexibility and scalability. Unlike relational databases, MongoDB stores data in collections as JSON-like documents.

In this blog, we’ll perform CRUD (Create, Read, Update, Delete) operations on a simple college student schema to understand MongoDB basics hands-on.

run all the commands in MongoDB Shell. this will work great.

Student Schema
We’ll use a collection called students, and each document follows this basic structure:

{

db.students.find()

Find all students with CGPA > 8:

db.students.find({ cgpa: { $gt: 8 } })
