Towards Quality Driven Schema Integrati...

If the structure ofinformation within several departments of an organization has to be integrated,the process of integration must meet quality criteria. In this paper, weaddress quality in the schema integration process, more specifically, qualitydriven schema integration process tasks. Therefore we searched the literaturefor the best practices used for conceptual modeling as such and applied theseto integration tasks. We address in particular three tasks within theintegration process that should improve the quality of the integrated schemawhen used with best quality practices. Within each best practice we emphasizethe use of knowledge repositories to support the process of creating a highquality schema. The three tasks are: choosing the right integration strategy,choosing the right conflict resolution methods for the chosen level ofabstraction and introducing inter-schema properties to improve and clarifydependencies.
