- dependency conflicts - connectivity is different for different views (e.g. job-title vs. job-title-history) - key conflicts - same concept but different keys are assigned (e.g. ID-no vs. SSN) - behavioral conflicts - different integrity constraints (e.g. null rules for optional/mandatory: insert/delete rules) * determine inter-schema properties
