I'm in a process of building an uml diagram for room booking system scenario. And I’m a bit stuck at the following paragraph.
"Some bookings will take priority over others: long series of lectures are harder to ﬁt in than one-off events, so sometimes the latter kind of booking is merely provisional until the former kind have all been settled; and anyway, the Head of Department has absolute power, and can (ask a secretary to) 1overrule any existing booking in favour of a later one that he deems more important."
As you see, there is a priority involved over when you book room for lectures in contrast to one-off event. But really the booking lectures have the priority.
I have a Booking class and members class and the relation between them is quite easy. But i cant really think of on how to represent the priority thing in any uml diagram. Any thoughts on how to?
Thanks very much guys!
