I would appreciate some help with attempting a question for an assignment which i am absolutely stumped on.
Can someone help determining if the below FD's are BCNF and if not, why are they not?
I need to understand why.
R1 (MemberID -> MemberFirstName, MemberLastName, Address, PostCode)
R2 (LoanID -> MemberID, BookID, LoanDate, ReturnDate )
R3 (BookID -> Title, Year, PublisherID)
R4 (PublisherID -> PublisherName)
R5 (AuthorID -> AuthorFirstName, AuthorLastName)
R6 (Title -> Year)
