1. Consider relation schema R = (A, B, C, D, E) and the following functional dependencies on. A BC CD E B- D E- A (a) List all candidate keys for FR. (b) Suppose that we decompose schema R into Ri-(A, B, C) and R (A, D, E). Show that the decomposition is a lossless-join decomposition (c) Give a lossless-join decomposition into BCNF of schema R
