+\section{Overview of the GNV-System}
+
+The GNV systems consists of the mainly 4 components, serving the
+following tasks:
+
+% FIXME: Add architecture of the system in english
+
+\begin{enumerate}
+\item Artefact-Server
+The Artefact-Server is a middleware component, managing the core tasks:
+\begin{itemize}
+   \item Access to the database backend
+   \item Providing a RESTful-Interface with a XML-based protocol to serve
+   \item the expert information systems (FIS) with their products
+   \item (diagrams like timeseries, verticalprofile, map layers) to make
+   \item them accessable for the GNV-WebClient
+   \item Processing of data for interpolation, classification and vectorisation
+   \item Configuration capabilities for FIS and products
+   \item Caching database result sets
+   \item Managing the WMS-Server for creating maps dynamically
+\end{itemize}
+
+\item Database Backend
+Database schemata like ESRI ArcMarineBSH, ArcS57 and CONTIS can be
+served out of a ESRI ArcSDE 9.3.1 database.
+
+\item WMS-Server
+The WMS-Server provides maps via the standardized interface of the OGC
+Web Map Service. The configuration is managed through the
+artefact-server depending on the parameterization done be the user in
+the GNV-WebClient
+
+\item GNV-WebClient
+The GNV-WebClient is a thin webbased client providing a HTML-based user
+interface for the user to parameterize the FIS and products via the
+XML-based protocol provided by the artefact-server through its
+RESTful-interface. Within the client the user can manage these tasks:
+\begin{itemize}
+  \item Select FIS, producs and their parameterisation
+  \item Visualize different diagrams like timeseries, vertical- and
+horizontalprofiles, vertical and horizontal cross-sections and map
+layers
+  \item Calculate and visualize (histograms) statistics
+  \item Export diagrams for printing in PNG, SVG, vectorized PDFs
+  \item Export data as in raw formats like CSV, Ocean Data View (ODV) and
+ESRI Shapefiles
+\end{itemize}
+
+The GNV-WebClient can be integrated with different MapViewers. The
+GNV-WebClients supports a XML-based interface to the MapViewers
+describung geometrical data and information about
+used layers in order to adapt the selection of FIS and areas of interest
+for the parameterization.
+\end{enumerate}
+
+The systems has been designed as a distributed system. This manual
+descibes the installation of a centralized system on one server for the
+middleware and an existing database server.
