+  \subsubsection{\textit{restaurant} -- server side}
+  The \textit{restaurant}\footnote{\textit{restaurant} is a pun on the word
+    \textsc{REST}} library is imported
+  as a normal Maven\cite{maven:website} dependency. It requires the
+  following dependencies:
+  \begin{description}
+    \item[Hibernate ORM\cite{hibernate:website}] a famous Java Object/Relation
+      Mapper\cite{wiki:orm}, used to query the \textit{PostgreSQL} database
+      with ease;
+    \item[GSON\cite{gson:website}] a library from Google for serializing and
+      deserializing Java object in JSON;
+    \item[Jersey\cite{jersey:website}] an implementation of the API JAX-RS
+      for creating REST endpoints, not through servlets but using
+      simple methods contained in plain classes, called \textit{controllers},
+      decorated with the annotations contained in the package \texttt{javax.ws.rs}.
+  \end{description}
+
+  The boilerplate needed to query the database is further simplified by the
+  code in \textit{restaurant} on two levels:
+  \begin{itemize}
+    \item It is possible to perform common CRUD operations\cite{wiki:crud}
+      and to build and execute custom queries by the static methods accessible
+      in the \textit{CRUDUtils} class. Those procedures work on the ``entity''
+      classes registered in the ORM;
+    \item In addition to what mentioned above, \textit{controller} can be
+      implemented with ease inheriting the abstract classes \textit{JsonProducer} (for
+      non-CRUD operations), \textit{ReadableRESTController} (for read-only CRUD
+      operations) and \textit{CRUDRESTController} (for complete CRUDs).
+      These components offer methods able to automatically generate both success
+      and error JSON responses. 
+  \end{itemize}
+
+  Below there are the interface listings for the classes \textit{CRUDUtils}, \textit{JsonProducer},
+  \textit{ReadableRESTController} and \textit{CRUDRESTController}, with the
+  respective Javadoc comments (in english, as in the original sources).
