Due to the complexity ofmo dern database applications, semantic information is no longer a unified whole, but arises from multiple sources. Whatever the type of the sources, information fusion raises the crucial problem ofin consistent sets ofin tegrity constraints. While earlier research mostly concentrated on consistency checking, less attention has been paid to the resolution ofcon straint conflicts in entity-relationship modeling. We suggest four strategies towards conflict resolution: (1) determination ofs uperfluous object types, (2) incremental consistency checking, (3) detection ofmi nimal inconsistent subsets, (4) constraint correction via feedback arc elimination, and apply them to constraint sets containing cardinality constraints and key dependencies.
