Welcome to MongoDB Session 01 by Rehan Kapaya!
This session is the perfect starting point for anyone who wants to learn MongoDB, understand the difference between SQL and NoSQL databases, and set up MongoDB properly on their system. If you are new to backend development, MERN Stack, or database systems in general, this video will give you a strong foundation and crystal-clear understanding of how modern databases work.
In today’s world, almost every web and mobile application relies on a database. But which one should you choose — SQL or NoSQL? What makes MongoDB so popular among developers? Why is MongoDB widely used in MERN Stack, backend development, real-time apps, dashboards, e-commerce systems, and cloud-native architectures?
In this session, Rehan Kapaya explains everything in a beginner-friendly way with real examples and easy-to-follow demonstrations.
We begin with database fundamentals — what a database is, why applications need it, and how data is stored, organized, and retrieved. You’ll learn how traditional SQL databases work (like MySQL, PostgreSQL, Oracle) and how they store data in tables, rows, and columns. Then we explore NoSQL databases and why they were created to solve modern scalability and data-structure problems. This leads into MongoDB — a flexible, document-based database built for modern applications.
After understanding the theory, Rehan Kapaya walks you through the step-by-step installation of MongoDB, installation of MongoDB Compass, and how to verify everything is working correctly on Windows. You’ll also learn what MongoDB Server, Mongo Shell, and MongoDB Compass actually do, and how to use them in real projects.
This video sets the stage for the entire MongoDB journey. In future sessions, you will learn CRUD operations, API creation, GET/POST/PUT/DELETE endpoints, MongoDB Atlas cloud setup, indexing, aggregation pipelines, and how to use MongoDB in full MERN applications. But everything begins with the foundation — and Session 01 by Rehan Kapaya builds that foundation in the most simple, clear, and practical way.
