Homework #1 Sample Solution
Note: This sample was created with System Architect, a rather expensive and cruddy (but UML compliant) CASE tool available on some CCS-maintained Andrew machines. If you can't get Softera (also pretty cruddy) to work on your machine at home, you might want to give this a try. I know for a fact that it's available on the first three rows of the cluster in Cyert Hall.
