Sample Use Case Diagram

The following sample shows a Use Case Diagram for an on-line CD catalog.  The system has a single actor: the on-line customer.  The customer can browse the catalog, search for a CD, add a CD to the order, view the order details, and place the order.

Both "View Order Details" and "Place Order" use "Calculate Order Total".
