I can't understand that in how the tuples are represented here in the relation R. How is it possible to have different tuples in one relation?
If I take R(B,C,D) that means relation R has three attributes i.e., B,C and D
so what does it mean
B:C:D
50,1,6
so does it mean that the attribute B has 50 tupples,attribute C has 1 tupple and the attribute D has 6 tupples?
