Abstract: Disaster relief operations are very different from the traditional war operations. In disaster relief operations everything has to go very fast, the relief workers have to leave on very short notice and cooperation with other organizations is needed in order to save as many human lives as possible. The communication and information system of those operations has to be small, flexible, rapidly deployable and mobile. Above that, it has to ensure the information exchange between the coordination center in the home nation and the relief workers in the field in all kinds of situations with changing bandwidths and impermanent connections. In this document the structure and the data warehousing of such an information system are described.
