Entities — Generic application agnostic data and business rules (e.g. Order, Customer ).
Interactors — Application specific business rules; Manipulates the relevant data from the Request Model and interacts with the Entities.
Boundaries / Gateways — Protocols or Interfaces.
Models — Dumb data structures, without methods.
- Request Model
- Response Model
- View Model
Controllers — Convert the stuff submitted by the delivery mechanism into a delivery agnostic Request Model.
Presenters — Turns the delivery agnostic Response Model into a prepared “viewbified” data structure ready for easy manipulation by the view.
- "… so the view is so stupid that you don’t have to test it!"
