What do I need to use for my project?

It's essential to choose the right repository for the project's needs, as it's not always necessary to use a database or keep information in memory, which could impact your project's performance.

To determine the type of repository you need, consider the following points:

• Will the data be reused on two or more servers? If it's only needed on a specific server, you could use JSON instead of a database.
• How frequently will my system be used? If your system will be used constantly, consider using in-memory storage, either dynamic or persistent, to access information efficiently.

Once you know which repository to use, it's time to learn how to use it in code.
