1) Parking Pay Station Using an activity diagram (UML), represent the actions of using an automated parking pay station. Customers activate the pay station by pressing the start button. The machine prompts for the license plate number, duration of parking and method of payment, which the customer provides. Customers can pay by cash or credit card. Credit card payments must be authorized by the bank. Once payment has been accepted/approved the machine dispenses the parking ticket which is then displayed on the customer's car dash.

2) Airline Passenger Check-In Using an activity diagram, represent the actions of checking in for a flight using the in-person check-in agent.

Upon arrival at the airport, the passenger provides their ticket or identification to the check-in agent. The agent locates the reservation and confirms the passenger is correct and that their passport is valid.( If either is invalid the check-in process is stopped.) The agent allocates the seat and at the same time updates the frequent flyer# by asking the passenger a security question. Once the answer has been verified the agent checks if the passenger has an extra bag(s) (extra bags require an extra bag payment) and prints the boarding pass. Once all bags are paid for and checked the passenger is allowed to proceed to security. When checking baggage: If the customer has only one bag to check it is weighed and assessed an overage fee if the total weight is greater than 50lbs. If the customer has more than one bag to check ALL bags are assessed the extra bag payment. Show both control and object flow for part 2
