Please be careful when asking questions about the lab on the list. A rule of thumb: if the question requires you to post any part of your solution you should probably ask a TA directly instead.

We have the relation:

AttendsBranch(*student*, branch, programme)
student -> Students.StudentId
(programme, branch) -> Branches.(programme, name)

What we are concerned about is if it is OK to instead have this relation:

AttendsBranch(*student*, branch)
student -> Students.StudentId
branch -> Branches.name

Since we may retrieve the programme that uniquely defines the branch from the StudentId attribute.

Are we way off?
