\section*{Question 9}

Consider the relation schema: $R = (A, B, C, D, E)$
with the following set F of functional dependencies 

\[
\begin{array}{ccc}

A & \rightarrow & BC \\
CD & \rightarrow & E \\
B &  \rightarrow & D \\
E & \rightarrow & A 

\end{array}
\]

Find the candidate keys for R

\section*{Question 10}

Consider the relation schema: $R= (A, B, C, D, E, F)$ 
with the following set F of functional dependencies:

\[
\begin{array}{ccc}
A & \rightarrow & ABCDEF \\
B & \rightarrow & C \\
D & \rightarrow & E \\
\end{array}
\]
 
Decompose this schema into a set of schemas that are in 3NF. The decomposition should be lossless-join.
