Question About Take Home Exam (all 4)

10:44am Mon 7th Oct, Kevin Z.

Good morning, In the take home exam, some questions ask "in the case study" and others ask "in the case study's EER model", does this mean that for questions which ask "in the case study" we have to refer exclusively to the case study description? Or could we also use the EER model provided to answer those questions? (perhaps I'm overthinking). Thank you for any insights, -Kevin

Same here I also wanted to know this. Because I faced something like "In the case study, what attribute would be primary key of..." and "In the case study, ... is always unique" While the ER specifies the specified field to be Primary Key, in the paragraph it was never mentioned to be unique (in fact, it is the other attribute that is explicitly stated to be unique in the paragraph) so I am currently a little bit confused on what to answer them with.

Yeah I'm confused too, the case study and ER diagram have some parts where they contradict each other even though the ER diagram is made from the case study.
