Suppose that we decompose the schema R = ( A , B , C , D , E ) into ( A , B ,

Suppose that we decompose the schema R=(A,B,C,D,E) into
(A,B,C)
(A,D,E).
Show that this decomposition is a lossless decomposition if the following set F
of functional dependencies holds:
ABC
CDE
BD
EASuppose that we decompose the schema r(A,B,C,D,E) into r1(A,B,C) and r2(A,D,E) Compute the closure and canonical cover of the set of functional dependencies A -> B C C D -> E B -> D E -> A
