MongoDB is a NoSQL database that stores data as JSON-like documents instead of rows in tables. Unlike traditional SQL databases that require a fixed schema upfront, MongoDB lets you store flexible data that evolves with your application. If you're building web applications, mobile apps, APIs, or need to handle large volumes of unstructured data, MongoDB is one of the most popular and practical choices today.

This tutorial series takes you from complete beginner to advanced MongoDB developer.
