Starting your way into the world of databases may seem intimidating at first; but with the right tools, such as MongoDB Atlas, this process becomes much more accessible and less expensive. MongoDB Atlas offers a free layer that allows beginners to get started without having to insert a credit card. This accessibility is ideal for those who want to learn and practice without worrying about costs.
To create a MongoDB Atlas account, follow these steps:
After these steps, you are ready to start configuring your environment in MongoDB Atlas.
Once your account is created, there are some initial configurations. First, you will be asked about the purpose of using the service and your preferred programming language, helping MongoDB collect data to improve the user experience. Next, choose the Free service option. Don't worry too much about infrastructure specifications at this stage.
During the setup process, you will need to provide a username and password that you will use to connect to your cluster. You will also need to set access permissions.
Importing sample databases will allow you to work with concrete information while you learn. MongoDB Atlas facilitates this process with just a few clicks:
Once the import is complete, you can explore different databases, such as Airbnb, to put into practice what you have learned during the course.
MongoDB Atlas offers a user-friendly interface that allows you to work with aggregations in two ways:
This dual approach ensures that regardless of your comfort level with the technology, you can advance your understanding and mastery of MongoDB.
Simultaneous use of MongoDB Atlas and a local MongoDB installation using Docker offers additional flexibility, especially in advanced features inaccessible in the free Atlas layer. Here's how to integrate it with Visual Studio Code:
The combination of these tools will provide a robust environment, allowing you to explore MongoDB in its full breadth, either in a more flexible local environment or in the cloud via Atlas. Go ahead, keep learning and exploring the world of databases!
