Introduction to MongoDB Basics

📖 Scenario: You are starting a new project to store information about your favorite books using MongoDB, a popular database system that stores data in a way similar to how you organize notes in folders.

🎯 Goal: Learn how to create a MongoDB collection and insert simple documents representing books.

📋 What You'll Learn

Create a MongoDB database named library

Create a collection named books

Insert at least two book documents with fields title and author

Use MongoDB shell commands or equivalent syntax

💡 Why This Matters

🌍 Real World

MongoDB is used to store flexible data like user profiles, product catalogs, or any information that changes often and doesn't fit neatly into tables.

💼 Career

Knowing MongoDB basics helps in roles like backend development, data engineering, and working with modern web applications that require fast, scalable databases.

1

Create the library database

Switch to the MongoDB database called library using the command use library.

MongoDB

# Switch to the library database
# Your code here

Need a hint?

Use the use command to select or create a database.

2

Create the books collection

Create a collection named books by inserting a document with title and author fields. Use db.books.insertOne() with the document { title: "1984", author: "George Orwell" }.

MongoDB

use library
# Insert the first book document into books collection
# Your code here

Need a hint?

Use db.collection.insertOne() to add a document.

3

Add another book document

Insert a second book document into the books collection with title as "To Kill a Mockingbird" and author as "Harper Lee" using db.books.insertOne().

MongoDB

db.books.insertOne({ title: "1984", author: "George Orwell" })
# Insert the second book document
# Your code here

Need a hint?

Repeat the insertOne command with the new book details.

4

View all books in the collection

Retrieve all documents from the books collection using db.books.find() to see the inserted books.

MongoDB

use library
db.books.insertOne({ title: "1984", author: "George Orwell" })
db.books.insertOne({ title: "To Kill a Mockingbird", author: "Harper Lee" })
# Retrieve all books
# Your code here

Need a hint?
