Model

• Proxies are used to get / set any data used in
  the app
• Data objects are the "business objects" used to
  store data used by the app.
• Delegates are used as the data input / output -
  call remote services

• Mediators are used as "observers" you can
  specify which Notifications (events) that they
  should handle
• View Components are UI components that are
  controlled by the mediators
