Boundary

Description:

The Boundary Pattern represents the design of the limiting edge of a system. Boundary demonstrates the perimeter frame or border that defines a system from its environment and that determines what may come into and what may go out of a system. Permeability, which allows the movement of elements into and out of the system, must be balanced with structural integrity, which defines the system through the separation of the elements inside and outside of the system.
