+	In the picture \ref{fig:itgmobliearch} is shown how the software components
+  in the app interact with each other. This architecture was entirely realized
+  by me, on the basis offered by the project \textit{InteGRa.Service}. Further
+  information is given in the following list.
+
+  \begin{itemize}
+
+  \item The smartphone app does not directly communicate with the accounting
+    software, but instead it interacts using \textsc{REST} calls\cite{wiki:rest}
+    with a middleware server application, named \textit{InteGRaREST};
+
+  \item The last component mentioned is a Java WebApplication, 
+    implemented by using an internally developed library named \textit{restaurant},
+    that contains the boilerplate needed to generate the \textsc{REST} routes
+    and to access the \textit{InteGRa} database, a normal \textit{PostgreSQL}
+    instance;
+
+  \item When information is exchanged by HTTP, input data is encoded
+    as \texttt{application/x-www-form-urlencoded}, while output data
+	  is encoded as \textsc{JSON}\cite{wiki:json}. Sessions are identified by
+    a token that must be included in the query string of each call;
+
+  \item \textit{InteGRaREST} queries the database autonomously through
+    \textsc{SQL} in order to fetch and store data structures with simple
+    or absent logical constraints;
+
+  \item When interaction with data arranged in complex structures is needed,
+    \textit{InteGRaREST} communicates with \textit{InteGRa} through
+    \textsc{SOAP} calls\cite{wiki:soap};
+
+  \item \textit{InteGRa Mobile}, the smartphone app, interacts with
+    \textit{InteGRaREST} thanks to a client version of \textit{restaurant},
+    which is able to handle offline operations.
