Question: Consider the relation schema R = { A , B , C , D } and the of FDs = { { A , B

Consider the relation schema R={A,B,C,D} and the of FDs ={{A,B}C,{A,C}B,DC}.
I.dentify a BCNF decomposition for R. You need to include the main steps .
2 There can be several different BCNF decompositions for R. Does there exist any BCNF decomposition that preserves all FDs in ? You must either find such a decomposition, and show that it is dependency-preserving,
or list all decompositions and show that each of them is not.
