The Database and Expert Systems Application (DEXA) Conferences are mainly held as state-of-the-art forums on database and expert systems applications. The sessions are application-oriented, ranging from classical applications to more unusual ones in software engineering. Actual research aspects in databases, such as activity, deductivity and/or object orientation are presented here, as well as the implications of the new data models such as the OO-model. Other areas of interest, such as hypertext and multimedia applications, together with the classical field of information retrieval, are also considered. Finally, implementation aspects are reflected in concrete fields.
