I hope you won't mind if I start a new thread for the subject. The other
thread has got quite long and somewhat off-topic.

So, the question is: what is the role of FDs (and possibly other types
of dependencies) in database design? My personal take:

In general, I don't think that it is possible for them to inform the
design activity since the early stages or that they should be used as
the main design tool. I do think, however, that when a system is
understood sufficiently well (e.g., by means of a conceptual design),
they offer an aid (are my schemas well-designed according to certain
criteria?) and insight (allowing us to possibly find alternative ways to
design a database, for example).

At an early stage, you probably cannot say: it might also be that desert
island and can opener should be represented as two relation schemas (for
which we have identified no attributes yet) related through a one-one or
one-many relationship. My point here is simply that FDs are not
invented, they are discovered.

(Not that it would necessarily be a good idea, I should add.)

Well no, like this certainly no :) Maybe something along these lines
(paraphrasing the given-when-then constructs existing in some testing
tools):

given two lecturers L1 and L2 and a time T
when L1 is teaching at time T and L2 is teaching at time T
then L1 and L2 are in different rooms

(this is absolutely off the top of my head: don't take it as a serious
attempt).

Could you provide a small example?
