Presentation Domain Separation

(PDS)

• Separate the display logic of the UI from the domain (Model) logic.

  • The domain refers to the essential part of the code that serves the purpose of the software.

• Separation of responsibilities.

• It is crucial to prevent the leakage of domain (Model) logic to the outside.

  • Pay attention to avoid leaking into UI logic, for example.
  • The reverse is also true.
  • This is also part of Domain-Driven Design, which involves isolating the domain from other layers.

• MVC, MVP, MVVM.
