TC 1TC 1• Review the external event checklist in Figure 5-3

and think about a university course registration system. What is an example of an event of each type in the checklist? Name each event using the guidelines for naming an external event.

• University Events:– External agent wants something requiring transaction:

Student submits registration request. – External agent wants information: Student wants to look

up open sections available– Data changed needs to be updated: Student submits

change of address information– Management wants some information: Department head

wants enrollment data for open sections.

TC 4TC 4• Consider the following sequence of actions taken

by a customer at a bank. Which action is the event the analyst should define for a bank account transaction processing system?

– (1) Kevin gets a check from grandma for his birthday – (2) Kevin wants a car – (3) Kevin decides to save his money– (4) Kevin goes to the bank– (5) Kevin waits in line – (6) Kevin makes a deposit in his savings account – (7) Kevin grabs the deposit receipt – (8) Kevin asks for a brochure on auto loans.

• Event customer makes a deposit (6)

TC 6TC 6• Draw a class diagram, including minimum and maximum multiplicity for the

following. The system stores information about two things: cars and owners. A car has attributes for make, model, and year. The owner has attributes for name and address. Assume a car must be owned by one owner and an owner can own many cars, but an owner might not own any cars (perhaps she just sold them all, but we still want a record of her in the system).

TC 8TC 8• Does this model

allow a student to enroll in more than one course section at a time?

• Does the model allow a course section to contain more than one student?

• Does the model allow a student to enroll in several sections of the same course and get a grade for each enrollment?

• Does the model store information about all grades earned by all students in all sections?

TC 12TC 12

• Refer to the class diagram for a bank in Figure 5-28. Expand the model to show that there are special types of customers – personal and commercial. All customers have a name and mailing address. Commercial customers have additional attributes for credit rating, contact person, and contact person phone. Personal customers have attributes for home phone and work phone. Additionally, expand the model to show that the bank has multiple branches, and each account is serviced by one branch. Naturally, each branch has many accounts.

• Draw a class diagram to extend the domain model that assumes there are different types of drivers. Classifications of types of drivers vary by state. Some states have restricted licenses for minors, for example, and special licenses for commercial vehicle operators.
