An Action is a named element that is the fundamental unit of an executable functionality. The execution of an Action represents some transformations or processing in the modeled system, be it a computer system or otherwise. An Action execution represents the run-time Behavior of executing an Action within a specific Behavior execution. As the Action is an abstract Class, all Action executions will be the executions of a specific kind of Action. When the Action will be executed and what its actual inputs will be determined by the concrete Action and the Behaviors in which it is used.
