Application Architecture

 ┌───────┐         ┌──────────┐       ┌──────────┐
 │   ☁️     <───>      ☕      <───>      💾    │

Internal Architecture

The internal architecture:

• Controller classes provide endpoints and deal with HTTP requests and responses from/to the view
• Service classes contains the business rules, receive the request from a controller and talk to repository to acess data to return a response to controller
• Repository classes interface with the DAO internally that interface with the database and take care of writing and reading data to/from persistent storage
