Mobile app package diagram

A mobile app package diagram shows the major modules in an application and how requests cross their boundaries. Presentation contains screens, domain contains use cases, data contains repositories, and network or platform packages hold external concerns. The arrows show direction: a screen invokes a use case, while the repository hides whether data comes from a cache or API. This is a concise way to discuss architecture in a design review before modeling the details of individual types.

FAQ

Questions fréquentes

Why separate domain from data?

It lets application behavior depend on an abstraction rather than a particular API or storage mechanism.

Can packages contain many classes?

Yes, but a package diagram usually shows only representative classes or names.

Should UI call the API directly?

Keeping that dependency behind a use case and repository makes the boundary easier to manage.
