How to install MongoDB on Ubuntu 20.04

MongoDB is one of the most popular NoSQL databases, it is open source and freely available to download. It stores data in the form of flexible documents like JSON rather than the usual table style method found in SQL databases. MongoDB is used to store and work on data without the use of schema or ordering patterns. The MongoDB NoSQL database is widely used in web applications because it has easier integration with various programming languages.

In this tutorial guide, I will show you how to install, run, and uninstall MongoDB on ubuntu 20.04.
