Give a lossless decomposition into BCNF of schema R of Exercise 7.1.

Exercise 7.1.

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:

A → BC
CD → E
B → D
E → A
