For this homework assignment, consider the schema R-(A,B.C,D, E) and the following set F of functional dependencies holds on R Problem 1. Suppose that we decompose the schema R into R (A,B,C) and R -(A,D,E) Show that this decomposition is a lossless-join decomposition with respect toF Problem 2. Suppose that we decompose the relation schema R into R, (,B,C) and R, -(C D.E). Show that this decomposition is not a lossless-join decomposition. Hint: Give an example of a relation r on schema R such that Problem 3. Compute (BC) Problem 4. Compute the canonical cover
