It illustrates the basic course of action of the 'edit item details' system use case. Note how different stereotypes are used to indicate actor, boundary, controller, entity and database objects.

The bitmap was created by exporting the file 'suc edit item details - basic course of action.trace' in the examples folder of your installation, at 72dpi and 100% scale in png format.
