Packages
In a typical application, these packages work together as follows:
User Interaction: The user interacts with the views (UI).
Request Handling: The controllers receive the input from the views and process it.
Business Logic: The controllers delegate the processing to the services, which contain the business logic.
Data Access: The services use repositories to interact with the database and retrieve or update models.
Object Creation: When complex objects need to be created, factories are used to manage the instantiation logic.
Helper Functions: Utilities provide common functionality to various parts of the application.
Response: The processed data is sent back through the service and controller layers to the views, where it is displayed to the user.
