How to create new database in mongodb

To create a new database in MongoDB, you can use the following methods:

Method 1: Using the MongoDB Shell

  1. Open the MongoDB shell by running the command mongo in your terminal or command prompt.
  2. Once you're in the shell, type the following command to create a new database:
    use <database_name>

    Replace <database_name> with the name of the database you want to create.

For example:

use mydatabase

This will create a new database named mydatabase if it doesn't already exist.

Method 2: Using the MongoDB Compass GUI

  1. Open MongoDB Compass, a GUI tool for interacting with MongoDB.
  2. Click on the "Databases" tab in the left-hand menu.
  3. Click on the "Create Database" button.
  4. Enter the name of the database you want to create in the "Database name" field.
  5. Click on the "Create" button to create the database.

Method 3: Using the MongoDB Command-Line Tool

  1. Open a terminal or command prompt and navigate to the directory where your MongoDB installation is located.
  2. Run the following command to create a new database:
    mongod --dbpath <path_to_database> --create <database_name>

    Replace <path_to_database> with the path where you want to store the database files, and <database_name> with the name of the database you want to create.

For example:

mongod --dbpath /data/db --create mydatabase

This will create a new database named mydatabase in the /data/db directory.

Method 4: Using a programming language

You can also create a new database using a programming language such as Python, Java, or Node.js. For example, in Python, you can use the pymongo library to create a new database:

from pymongo import MongoClient

client = MongoClient()
db = client["mydatabase"]

This will create a new database named mydatabase if it doesn't already exist.

Note: Before creating a new database, make sure you have MongoDB installed and running on your system.
