How to Create Database and Collection in MongoDB

In this MongoDB tutorial, You will learn how to create database and collection in the MongoDB server using the MongoDB compass application and MongoDB shell with the help of the examples.

MongoDB does not provide any ‘create‘ command to create databases like traditional SQL databases like MySQL, SQL Server, and PostgreSQL.

Note:- Databases in MongoDB indicate the databases in SQL Like databases engines and collections in MongoDB indicate the tables in the  SQL databases engines like MySQL, SQL Server, and PostgreSQL.

Let’s see the process of creating a database and collection in MongoDB using a compass and Mongodb shell.

Make sure You have installed the MongoDB NoSQL server on your machine.

Create Database and Collection using MongoDB Compass

MongoDB Compass is a GUI ( Graphical User Interface ) application to manage MongoDB databases like creating databases, creating collections, creating documents, deleting databases, delete collections, and documents.

MongoDB compass is a very easy-to-use application, you don’t need more technical knowledge to use this application, You need to follow some basic steps and things will already happen.

Let’s start.

• Open MongoDB Compass Application. Click on the Connect button to connect to the MongoDB server.

• Now, You need to click on the Plus Icon in the left side panel to create a Database and collection.

• Provide database name and collection name, In my case database name is ProgrammingFunda, and the collection name is an employee and after that click on Create Database.

• Now, the Created database will appear on the left side as you can see below and collections will appear inside the database.

This is how you can create a database and collection in MongoDB using MongoDB compass. Now, Let’s see how we can create using MongoDB shell.

Create Database and Collection using MongoDB Shell

MongoDB Shell:- MongoDB shell is a command line interface to manage database-related tasks and you can perform administrative tasks. You can perform almost all the operations that you can perform from the MongoDB Compass application.

Let’s create a database and collection using MongoDB shell.

• Open the command prompt in your machine and type ‘mongosh‘ to enter into the mongo shell.

• After entering the MongoDB shell, There is no ‘create‘ command to create a database. You need to use the ‘USE DATABASE_NAME’ command to create the database inside the MongoDB. Replace DATABASE_NAME with your database name. In my case, the database name is ‘ProgrammingFunda‘. After using the ‘USE DATABASE_NAME‘ command, you will switch to provide the database name.

• Now, let’s display all the databases using the show dbs command. As you can see below. The ‘ProgrammingFunda‘ database is not showing because MongoDB only creates the database when you store content inside that database. The data could be a collection or a document.

• To create a collection in the database, you can use the createCollection() function and pass the collection name inside that function. In my case, I am creating an employee collection name as you can see below.

• Now, let’s display the database name again by using the ‘show dbs‘ command, and this time ‘ProgrammingFunda‘ database is showing as you can see.

So this is how you can create database and collection in MongoDB using MongoDB shell.
