Draw a sequence diagram showing the interactions of objects in a group diary system, when a group of people are arranging a meeting.
What will be an ideal response?
The above diagram assumes there are 3 participants in the meeting, one of whom is
the meeting organizer. The organizer suggests a ‘window’ in which the meeting
should take place and the participants involved. The group diary communicates
with the diaries of the participants in turn, modifying the window accordingly as
there availability is known. So, if the organizer suggests a window of 18th-19th
June, the group diary consults the organizer’s diary (D1) and finds availability on
these days. D2 is then contacted with that availability, not the original window.
If there are no mutually available dates in the window, the system reports
this to the organizer. Otherwise, a date is selected, entered in all diaries and
confirmed to the organizer.
