Welcome to Hands-On Introduction to NoSQL with MongoDB — a beginner-friendly and practical course designed to help you understand what NoSQL is, how MongoDB works, and how to start using it in official GUI, as well as from the shell and in code.
I’m Lucas — a tech lead working in an international team — and I’ve created this course for developers, DevOps engineers, and curious learners who want to understand how to use NoSQL databases effectively.
In just around 2 hours, you’ll get a clear and hands-on introduction to MongoDB — from installation to core CRUD operations, data modeling strategies, indexing, aggregation, and real-world usage with Node.js.
No slides. Just coding and real examples.
So no matter if you’re a complete beginner or coming from SQL, you’ll learn:
What NoSQL means and how it compares to relational databases
Why MongoDB is one of the most popular NoSQL databases today
How to work with databases, collections, and documents
How to perform powerful operations using shell commands and aggregation pipelines
How to connect and use MongoDB from Node.js using the official driver
By the end of this course, you’ll be confident using MongoDB for your own projects, prototyping, or backend development.
All tools used are free — and everything we build can run locally or in the cloud with MongoDB Atlas.
So let’s get started!
