1. To what events must the MLS system respond? List each event, the type of event, and the resulting use case. Be sure to consider all the use cases that would be needed to maintain the data in the MLS system, thinking in terms of the CRUD technique.

2. Draw a use case diagram based on the actors and use cases you identified in question 1.

3. Using the event decomposition technique for each event you identify in the description here, name the event, state the type of event, and name the resulting use case. Draw a use case diagram for these use cases.

4. Consider the new Social Networking subsystem that SBRU is researching. Think in terms of the user goal technique to identify as many use cases as you can think of that you would like to have in the system. SBRU is guessing you might want to join, send messages, and so forth, but there must be many interesting and useful things the system could do before, during, and after the trip. Draw a use case diagram for these use cases.

5. From this description as well as the information from Chapter 2, identify all the actors that will be using the system.

6. Using the actors that you identified in question 1, develop a list of use cases based on the user goal technique. Draw a use case diagram for these use cases.

7. Using the event decomposition technique for each event you identify in the description here, name the event, state the type of event, and name the resulting use case. Draw a use case diagram for these use cases.

8. Identify all the actors that will use RTGM.

9. Using the actors that you identified in question 1, develop a list of use cases based on the user goal technique. Draw a use case diagram for these use cases.

10. Using the event decomposition technique for each event you identified in the description, name the event, state the type of event, and name the resulting use case. Draw a use case diagram for these use cases.
