Case 1: Create a use case diagram based for the system that follows. Consider the following Pet Groomers Appointment system: When making a booking, pet owners need to fill a booking form that states their name, address, phone number, and the pets' details such as pet name, breed and age. Owners will also enter their preferred date of appointment such as day and time. The admin receives the booking form and checks the groomer's schedule to see whether the time slot is booked. If the slot is free, the booking is scheduled and confirmation will be given. However, if the slot is booked, the admin will suggest the next available slot based on the day and time entered. If the pet owner agrees, they will confirm the booking and it will be scheduled. An assigned groomer will receive the booking under their schedule. The system will send a reminder to the owner 3 days before their appointment.
