The student needs to login to the system by inputting their student ID and password. The system uses that student ID to retrieve the intake of the student and based on their study plan, the system will display a list of subjects the student can register.

A company hires out tools and equipment to customers and requires a computerized system to record details of bookings. The customer appears at the reception desk and ask if there is an item available for immediate hire. When dealing with a booking or allocating an available item to a customer, the receptionist has to check whether the customer has previously hired equipment from the company or is a new customer. For a new customer, the receptionist has to enter the customer's details. Otherwise, the receptionist has to retrieve the existing customer's record and update any details if necessary. If the item is available then the customer can get it, otherwise, the receptionist might suggest other alternatives. If the alternative is accepted, then the receptionist allocates the tool and updated the customer record. Draw an activity diagram that models the data processing of hiring.
