So far, most inter-database relationship conflicts are addressed at the schema-level by various schema integration techniques. However, instance-level relationship conflicts are largely neglected.  ...  In this paper, we discuss relationship conflicts as a special type of conflicts to be resolved during the database integration. Relationships are properties that relate real world objects.  ...  Acknowledgements The authors wish to thank the Editor-in-chief and the anonymous reviewer for their very supportive comments during the preparation of this manuscript.  ...
