Flexible querying and temporal databases

Due to the increasing complexity of applications in the field of multimedia information systems, new querying techniques need to be studied in order to make them better to satisfy user needs. Our aim is to define a general model to facilitate retrieval of multimedia data in the context of object-oriented databases. With this model, the user expresses his preferences and then, the answers to a query are presented from the most pertinent to the least. We show that systems which manage temporal aspects of multimedia data need such a model and we propose that the definition of 'fuzzy' temporal predicates be integrated in the general model.
