QUESTION Check if lossless and dependency preserving R = {A,B,C,D,E} R1 = (A, B, C) = R2 = (A, D, E) FD: A - BC, CD - E, B D, E - A I solved it but when I checked my work the answer was a little different R1 FD: A -> BC, BC -> ABC R2 FD: A -> DE, E -> AD From R14 R2: BC->ABC, E -> AD are lost From R: CD -> E, B -> D are lost But the answer only stated that CD-E and B->D are lost Are BC->ABC, E->AD not lost? Or do they not matter
