Identify possible objects in ONE of the following systems and develop an object-oriented design for them. Using a UML class diagram and associated explanation to show your design. You may make many reasonable assumptions about the system when deriving the design.       A group diary and time management system is intended to support the timetabling of meetings and appointments across a group of co-workers. When an appointment is to be made that involves a number of people, the system finds a common slot in each of their diaries and arranges the appointment for that time. If no common slots are available, it interacts with the user to rearrange his or her personal diary to make room for the appointment.       A filling station (gas station) is to be set up for fully automated operation. Drivers swipe their credit card through a reader connected to the pump; the card is verified by communication with a credit company computer, and fuel limit is established. The driver may then take the fuel required. When fuel delivery is complete and the pump host is returned to its holster, the driver's credit card account is debited with the cost of the fuel taken. The credit card is returned after debiting. If the card is invalid, the pump returns it before fuel is dispensed.
