Getting Started

Once MongoDB is installed and running. Use mongo shell. Just open up your terminal and enter mongo. You will be presented with Mongo Shell. If you have turned on Authentication then use the following parameters to the mongo command. This will prompt you for the password. Now you can view list of all databases using show dbs command. You switch to whichever db you want or even create a new db. You can see list of collections in the current database using simple command show collections;

What are collections in MongoDB?

They are simply group of objects which represent something similar. For analogy, its just like a Table / Relation in a Relational Database like MySQL.

What are documents?

Documents are to MongoDB what Row is for Relational Database. Documents are nothing but collection of key value pairs(actually more than that, but this is what you should know for now).
