MongoDB Commands Cheat Sheet

What is MongoDB?

MongoDB is an open-source document-oriented database that is designed to store a large scale of data and also allows you to work with that data very efficiently.

Features of MongoDB

1. It is a natural form to store data.
2. It is human-readable.
3. Structured and unstructured information can be stored in the same document.
4. You can nest JSON to store complex data objects.
5. JSON has a flexible and dynamic schema, so adding fields or leaving a field out is not a problem.
6. Documents map to objects in most popular programming languages.


As a MongoDB novice, you’ll find a thorough list of all the MongoDB commands you’ll ever need in this post. This list includes practically all of MongoDB’s most often used commands.
