MongoDB – Create Database

In MongoDB, a database is created by simply connecting to it and using it. MongoDB will automatically create the database when you first insert data into it. Below is a step-by-step guide to creating a database for an insurance company in MongoDB.

1. Start MongoDB Server

Before proceeding, ensure that your MongoDB server is running. If you’re using MongoDB locally, open a terminal and run:

mongod

This will start the MongoDB server and make it ready to accept connections.

2. Open Mongo Shell

To interact with MongoDB, open a new terminal window and run the following command:

mongo

This will open the Mongo shell, where you can execute MongoDB commands.

3. Create a New Database for Insurance Company

To create a database for an insurance company, follow these steps:

a. Select or create a new database:

In MongoDB, a database is created automatically when you first insert data into it. You can select a database by running the following command:

use insuranceDB

If the database doesn’t exist, MongoDB will create it when you insert the first document.

b. Create Collections:

Now that the database is created, let’s define some collections for the insurance company. For an insurance company, you might want to create collections such as:

• Customers: To store customer information.
• Policies: To store insurance policies issued to customers.
• Claims: To store claim information for policies.
• Payments: To store payments made for premiums.
