\subsection{Checklist}
The following things are typically important to know very well (not exhaustive)
\begin{todolist}
    \item SQL (syntax, some concepts, such as using \texttt{WITH} statements often to make the task more approachable)
    \item Functional Dependencies (including Candidate Keys, Super Keys, Closures and minimal covers)
    \item Normal Forms (and their Decomposition / Synthesis Algorithms)
    \item Time complexities, I/Os and sorted runs for Query Processing
    \item Conflict Serializability
    \item Recoverability (both the normal techniques, plus Snapshot Isolation and 2-Phase Locking (and strict variant thereof))
\end{todolist}
