Term Definition: implementation subsystem

A collection of components and other implementation subsystems used to structure the implementation model by dividing it into smaller parts. Note that in the RUP, the implementation model and the implementation subsystems are the target of the implementation view and are, therefore, of primary importance at development time. It is the physical analogue of the design package. The name "implementation subsystem" reflects a common usage of the term "subsystem" to indicate something of a larger scale than a component. In UML terms, however, it's a stereotyped package, not a subsystem.
