Upload your answers in the appropriate format to your student directories.

Read chapters 5 and 6 of Fowler and then answer the following questions.

Chapter 6 talks about a number of the more obscure aspects of UML
diagrams and are used much less frequently.  Read this chapter lightly
so that you are aware of the concepts and have some idea about where
they might be useful.  You can read about them in more detail when you
need the information.  The questions about chapter 6, below suggest the
level of understanding you should be acquiring in your reading and in
class.

1. What kind of system behavior is modeled by interaction diagrams? 
Describe one example of such behavior and how it is modeled.  Your
example should involve at least three classes and at least for
interactions.

2. Draw an interaction diagram for the example you gave in response to
question 1.

3. Collaboration diagrams are used to model the same kind of system
behavior as interaction diagrams but they emphasize different aspects of
system behavior.  How are the two diagrams different?

4. Draw a collaboration diagram for the example you gave in response to
question 1.

5. How are interaction and collaboration diagrams the same?  How are
they different?  Assume that readers of your answer know what the two
diagrams look like so that you can concentrate on the different emphasis
of the two diagrams.

6. What are CRC cards?  How are they used in system analysis and design?

7. Compare and contrast the information presented in figures 6-1 and
6-2.  When would you use these two diagrams?

8. In narrative form, describe the information conveyed by figure 6-4.

9. What are derived associations and attributes?  Give an example of each.

The named individuals are to present their answers to the question with
the number shown.

I will bring transparencies of Figures 6-1, 6-2, and 6-4 to class.
