Semantics A System Boundary is a type of partition that represents the boundary between the thing you are representing with the use cases (inside the boundary) and the actors (outside the boundary). Its most typical usage is the boundary of an entire system. Use cases can be used to represent subsystems and classes and so the boundary may be more specific than an entire system. A package with a stereotype topLevel can be used as a boundary and name space within the use case model to denote the same thing as the use case boundary. Procedure for creating system boundary In order to create system boundary, click [Toolbox] -> [UseCase] -> [System Boundary] button, drag from the starting point of system boundary and drag to right-bottom point of system boundary.
