Unanswered: ER diagram from functional dependencies
looking at question b), how do you draw an E-R diagram from a bunch of functional dependencies?
I mean, where do you start? Can I just pick, say, E to be the starting point and have branches coming out to all the other attributes? I have no idea
This is a nice example of the "Wally Period"(*): it's the period between getting an important, urgent task from management and the time they need to change their whole mind and give you another important, urgent task. They will never ask you about that previous task, as it's no longer important. Any time and effort you've spend on the previous task is lost and will never be rewarded.
