MongoDB: Show Database

In our previous tutorial, we have created a database called books.

In MongoDB, a database is composed of collections and a collection is composed of documents.

We first start MongoDB.

If you are using a Mac, open your terminal and start the Mongo Daemon first. 

				
					$ mongod

Next, open a new terminal and start the Mongo Shell. 

				
					$ mongo
mongod and mongo shell

This will open up the Mongo Shell from where you can input your commands.

But if you system runs on Windows, navigate to the /bin directory and double-click on the Mongo Daemon mongod.exe. Next, in the same /bin directory, double-click on mongo.exe. This will start the Mongo Shell for command inputs.

Now there already exist some default databases in MongoDB, like admin, config and local . When you list all the databases, they will show along with the database/databases you created. The below commands 

				
					$ show databases

or 

				
					$ show dbs

will list all the databases along with the admin, config and local default databases.
