1. To what events must the ticket-processing system respond? List each event, the type of event, and the resulting use case.

2. Write a brief use case description for each use case.

3.  The portion of the database used with the ticket-processing system involves driver data, ticket data, officer data, and court data. Driver data, officer data, and court data are read by the system, and the ticket-processing system creates and updates ticket data. In an integrated system like the ticket-processing system, some domain classes are created by and updated by other systems, as described in this case. Create a table with systems down the rows and the four types of data (domain classes) across the columns. Indicate C, R, U, or D for each domain class and each system.
