Question: Given the relation schema R ( A , B , C , D , E , F ) and the functional dependency set F =

Given the relation schema R(A, B, C, D, E, F) and the functional dependency set F ={B D, E F, D E, D B, F BD}. Is the decomposition of R into R1(A, B, D, E) and R2(B, C, D, F) lossless join? Explain your answer, if not, what functional dependency could you add to make it lossless join?
