MongoDB installation and setup - Mini Project: Build & Apply

MongoDB Installation and Setup

📖 Scenario: You have MongoDB installed and need to verify it's working by connecting, creating a database, inserting a document, and querying it back. This confirms your installation is properly configured.

🎯 Goal: Connect to MongoDB, create a database and collection, insert a document, and query it to verify the setup is working end to end.

📋 What You'll Learn

Connect to MongoDB and switch to a new database

Create a collection by inserting a document

Query the document back to verify it was saved

Check database and collection statistics

💡 Why This Matters

🌍 Real World

Verifying a MongoDB installation with basic CRUD operations is the first step before building any application on top of MongoDB.

💼 Career

Every MongoDB developer needs to know how to create databases, insert documents, and query data using the shell — it's the foundation for all MongoDB work.

1

Switch to a new database

Use the use command to switch to a database called myapp. MongoDB creates the database automatically when you first store data in it.

MongoDB

// Switch to the myapp database
// Your code here

Need a hint?

Type use myapp in the MongoDB shell to switch to or create the database.

2

Insert a document into a collection

Use db.users.insertOne() to insert a document with fields name set to "Alice", email set to "[e-mail]", and age set to 30.

MongoDB

use myapp

// Insert a document into the users collection
// Your code here

Need a hint?

Use db.users.insertOne({ key: value }) to insert a single document into the users collection.

3

Query the document back

Use db.users.find() with a filter of { name: "Alice" } to retrieve the document you just inserted.

MongoDB

use myapp
db.users.insertOne({ name: "Alice", email: "[e-mail]", age: 30 })

// Find the document by name
// Your code here

Need a hint?

Use db.users.find({ name: "Alice" }) to search for documents matching the filter.

4

Check database statistics

Run db.stats() to check the current database statistics, confirming data was stored successfully. Then run show collections to list all collections in the database.

MongoDB

// Run database stats and list collections
// Your code here

Need a hint?

Use db.stats() for database statistics and show collections to see all collections.
