Homework #2 Sample Solution
Note: As with the Homework #1 sample, 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.
Problem #1: Extending the Hotel model with Amenities
and Seasons (a and b combined)
Problem #2.a: User Authorization Diagram with
Problem #2.b: User Authorization Diagram without
Problem #3: Comparison of Association class
notation v. conventional notation
The two diagrams shown below problem 3 mean exactly the same thing.
The only difference is that when the association class is explicitly given
using new notation, the relationship between the two primary classes involved
becomes more clear. However, using such less common notation may
impact the readability of your diagram if your audience does not have heavy
UML experience. For the purposes of the assignment, any reasonable
comment on their differences received full credit.
Problem #4: Church System
Note: Again, no sample is being provided, since this assignment
builds on your later project work.
