Given the use case, domain model, and system sequence diagram from the previous homework

assignments for the diner's automated cash register $...$

Write the software for an automated cash register at Mark's Diner in the Student Union.

The primary actor is the cashier and the customer is paying by Comet Card, credit card,

or cash.

You may assume no special requirements, and that the only technology list item is

processing a Comet Card or credit card.

a$)$ Create a design class diagram.

b$)$ Create a sequence diagram.

Grading Rubric

Each of the two parts is worth $50$ points.

A reasonable set of design classes, $10$ points.

Design class diagrams have all three compartments with reasonable attributes and operations, $20$

points.

Every design class should have at least one association with at least one other design class, $10$

points

Reasonable multiplicity for associations, $10$ points

The sequence diagram objects should match, at an appropriate level of abstraction$,$ the classes in

the design class diagram, $30$ points

A reasonable set of messages, corresponding to methods, should connect objects collaborating in

the sequence diagram, $20$ points

Note that sequence diagrams model the interactions between the objects implementing the

system $-$ it is not an SSD$.$
