QUESTION 2 Not yet answered Marked out of 25.00 P Flag question Draw a UML sequence diagram using the provided class diagram for a car dealership and the following use case. The specifications below describe the interaction among system objects when performing one of the system's use cases. This use case explains a customer booking a MOT service. Preconditions of this use case: The customer already logged-in and several objects already exist in the system memory. Some of these objects are GUI (an object representing the graphical user interface of the system), customer (instance of Customer), registry (instance of Registry), mechanic (instance of Mechanic). Download and work on this VPP file which includes the class diagram (click here). 1. The customer selects a date (for MOT) using GUI. 2. GUI calls the customer object to search for a service for the given date. 3. The customer object calls the registry object to find the available service times. 4. The registry calls all mechanic objects to get their availability. 5. The registry returns the list of availabilities to the customer object and the customer object returns it to the GUI. 6. If the returned list is empty, then GUI displays (the customer) no available slots message. 7. Otherwise, GUI display available slots to the customer. 8. Then customer selects one of the available slots from the GUI. 9. GUI calls the customer object to book an MOT service. 10. The customer object calls registry to create an MOT service for the selected date and time. 11. The registry object creates a new MOT object and adds it to the mechanic's schedule. 12. The registry returns the MOT object to the customer object and the customer object returns it to the GUI. 13. GUI displays service details to the customer. HINTS: You can use List notation for your return messages where a lifeline returns of a list of objects. Please use the names below for the actor name and messages in your diagram: Customer, select date, no available slots, display available slots, select a slot, display service details Create your UML sequence diagram using Visual Paradigm and when done save it as PDF. Then, upload the PDF file to the section below by dropping the file into it or using the add file icon on the top left
