Research and development in database technology evolves in several directions, which are not necessarily divergent. A number of these directions might be promising for military information systems as well. In this paper, we discuss the potentials of multi-media databases and data mining. Both directions focuss on the handling of a vague information need of a user. In general, data mining systems allow a higher degree of vagueness than multi-media systems. Information systems that are able to handle vague information needs adequately will improve the decision making process of militaries.
