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.
