%   4NF intuitively: do not store unrelated information in the same relation.

    The following table shows for each employee:
    \begin{itemize}
      \item knowledge of programming languages
      \item knowledge of programming DBMSs
    \end{itemize}
    \begin{center}
      \tableKnowledge
    \end{center}
    \pause
    There are no non-trivial functional dependencies.
    \begin{itemize}
      \item The table is in \emph{BCNF}.
    \end{itemize}
    \pause
    Nevertheless, there is \emph{redundant information}.
