Database Design

Can anyone give me a hand, i know it will be pretty basically and i've been to stack overflow already. But im pretty noob at database design/relations etc.All I need is to calculate the closure for A+ and E+

G = {A, B, C, D, E, F, G}

with the following FD's
1) B -> ACDE
2) E -> FG

Any help would be appreciated.

Well, since closures over transitive relations are the most common that you can find on every CS text, we can speak about closures instead of transitive closures.
