Modeling of Output Constraints in Multimedia Database Systems

Abstract

Constraints are used in traditional database systems to define consistent database states. For multimedia data it is also important to define constraints for a correct data output. The producer of multimedia data should specify constraints for a correct data output. We show the modeling of output constraints. The multimedia database system must guarantee that the stored multimedia data and the data output of multimedia data are according to the defined output constraints. For that an efficient check of output constraints must be possible.
