For a simpler handling of the data all needed measured values are stored in a \ac{ORDBMS}, more precise in a \acs{PostgreSQL} database. The available tables, their fields and relations
are shown in Figure~\vref{database:fig:structure}.

is also a webfrontend to get with a \ac{SQL} command data from the database---this is restricted to the \ac{ETH} computer network. Another webfrontend has been created to load data into the database.
