Abstract. We discuss an approach to collaborative data management based on uncertain databases. Note that, in a collaborative data management system, users may have contradicting opinions about the correct values of data items. In our approach, we propose to store all conflicting data versions in parallel and to resolve conflicts based on user ratings. We show that such a collaborative data management system can be nicely represented in an uncertain database using U-relations. 1
