No I don't think you're wrong, it's a lot of busy work for a few marks. I felt the same way about this question. The kids would have needed to evaluate the possible combinations to produce an answer that would need less rows to save writing time.

Hi all,



Not sure I like this question at all. Normalising to 1NF sounds simple enough, particularly when students are required to use just one set of sample records, but this seems like it requires a lot for 3 marks:



Choosing the first record (fancy_cat), here's what I think would be required for full marks:


userName

fullName

interestGroup

contactList

fancy_cat

Francine Ulas

love_planes

paperclip55

fancy_cat

Francine Ulas

love_planes

panic_disco

fancy_cat

That's 15 individual records students would have to write out, unless I'm mistaken. Will students be penalised if they do the sensible thing and normalise this data to 2NF by creating separate tables?



I thought I understood normalising to 1NF, but perhaps I'm wrong. The addition of that 4th field (contactList) has seemingly made this a big challenge (15 lines of writing) for just 3 marks.



I'd appreciate feedback/corrections from others on this question, since it has me somewhat confused.



Cheers,

Gary
