| Tiivistelmä: | In the process of integrating legacy databases, there are inter-database conflicts to be resolved at both the schema and instance levels. This paper discusses relationship conflicts as special type of conflicts to be resolved during the database integration. This paper also investigates the causes of instance-level relationship conflicts and proposes a taxonomy for classifying instance-level relationship conflicts. In addition, a systematic process is developed to resolve instance-level relationship conflicts and incorporate the resolution steps into the overall database integration process. This research ought to facilitate database integration work for both multidatabase and data warehousing approaches. Most importantly, it should improve the data quality of the integrated databases. |
