Presentation Abstraction Control

From PoSa:

''The PresentationAbstractionControl architectural pattern (PAC) defines a structure for interactive software systems in the form of a hierarchy of cooperating agents.

Every agent is responsible for a specific aspect of the application's functionality and consists of three components: presentation, abstraction, and control.

This subdivision separates the human-computer interaction of the agent from its functional core and its communication with other agents.''

See page 27 for further explanation of the PAC pattern, as well as
