I have one more question, just wanted to verify if my model is correct. Following is the equipment
So I had an original design with the class Room which was further extended to seminar, laboratories, a video-conferencing suite and etc.
The primary use of the system will be for room bookings—for seminar and meeting rooms, laboratories, a video-conferencing suite,
social spaces, and so on. The various rooms have different characteristics—capacity, whiteboard space, different kinds of
computer, video cameras and ﬁxed projectors, water heaters, etc.
The portfolio of rooms changes rarely, but the portable resources change frequently."
But after I second requirement change it to the second design. But you see with the latter design, it clearly states, when you create a new room, there is always a portfolio attached to it, so that i could be anyone of room which is states above. Whereas if the former design lacks this sort of information. Please validate and do let me know what you think of it?
