Consider relation R(A,B,C,D,E) with functional dependencies:AB -> C, C -> D, BD -> EWhich of the following sets of attributes does not functionally determine E
Question
Solution 1
The functional dependencies given are AB -> C, C -> D, BD -> E.
To functionally determine E, we need either BD or a combination of attributes that can derive BD.
From the given functional dependencies, we can derive BD from AB (since AB -> C and C -> D, we can derive BD from AB).
