Draw a sequence diagram showing the interactions of objects in a group diary system, when a group of people are arranging a meeting. Assume that 3 participants must participate in the meeting. Each participant has a diary (For example D1, D2, D3) and the meeting has to be scheduled in the group Dairy (G). The organizer (Participant 1) has to consult the two participants and then settle on a date and time for the meeting. Assume that a group dairy and time management system is used for setting up the appointments. When an appointment is to be made by Participant 1, the system finds a common slot in each of their dairies and arranges the appointment for that time.
