ICT340: Formulate a use case diagram to depict the cinema ticketing system design. Your use case diagram should show: Application Analysis and Design Assignment, SUSS

Question 1a

Formulate a use case diagram to depict the cinema ticketing system design. Your use case diagram should show the actors, the use cases, and their relationships.

Question 1b

The following is an extract of the requirements of the cinema ticketing system: “The self-service kiosk is a convenient way for concession holders to buy movie tickets. The system allows tickets to be sold at different prices depending on concession holders. All concession holders need to enter their age to be eligible for the concession. They are also entitled to buy popcorn at a discounted price of $3. A customer who buys a ticket for his 5-year-old child for a 2D movie to be screened on Wednesday has to pay $7.”

Question 2a

Complete the class description by identifying classes, their attributes and any
hierarchical relationship(s) that would be required for the application.

Question 2b

Appraise the associations among the classes and hierarchical relationship(s) that would be required for the application. Construct the class association diagram in UML as your answer. Ensure that you do not include any derived or redundant association in your diagram.

Question 3

Further analyses, as well as a few walkthroughs, give rise to an updated class diagram, part of which is shown in Figure Q3 below.

Note that this may not be applicable to Question 2 above.

Consider the following walkthrough:

Objective: To cancel a purchase

Given: A purchase number.

Locate the instance, purchase, of Purchase with the given purchase
number, linked to the orchestrating object via purchases.
Retrieve the list of screening dates/times of the tickets in the purchase via
consists.
For each screening date/time,
3.1 If the screening is not yet screened,
3.1.1 Update the seat remaining for the movie screening.
3.1.2 Change the purchase status to “Cancelled”.
3.1.3 Retrieve the amount to refund.
3.1.4 Add the amount to the total.
3.1.5 Return the total amount to refund

Question 3a

Develop the dynamic model for the application function, by drawing the sequence diagram for the walkthrough to cancel a purchase.

Question 3b

Implement the method in the following classes that is responsible for canceling a purchase:
(i) The orchestrating class
(ii) The Purchase class

Question 4a

Develop a structural model of the system that uses the strategy pattern by constructing the class association diagram (including operations; attributes are not required) that shows the ticket prices for customers.

Question 4b

Implement the Context class and its subclasses, the Strategy class, and the Strategy subclass for the Adult ticket for the structural model in Q4(a).
