Guidelines for a sustainable water quality and quantity have been defined and measures shall be started by end of 2009, accordingly. By 2015, all the selected natural water bodies must have reached a “good quality” status taking into account both chemical and biological water observations. Against the backdrop of the WFD requirements, but also in order to exploit potentials of efficiency and quality of new IT technologies, the German federal states of BadenWürttemberg, Bavaria and Thuringia have decided to cooperate for the development of the water information system “FIS Gewässer”. Since 2002 FIS Gewässer has been extended and adapted to state-specific deployments. An important role in this cooperative project plays the foundation of a common system architecture as well as the development framework XCNF (Extensible Database Application Configurator) that enables customisation and the implementation of a large portion of state-specific needs just by configuration.Text/Conference Paper
