Bridging the Gap between Comparison and Conforming the Views in View Integration

View integration is a complex, error-prone and time-consuming task. Therefore there is a need to decompose the integration methods into smaller well defined phases where different techniques are applied. Most of the methods used today is composed of, or at least is a mixture of, the following four phases: pre-integration, comparison of the views, conforming the views and merging and restructuring, and most of the methods put focus on phase 2 and 3. Despite of this there is a gap between these two phases. To bridge this gap a framework has been developed. In the framework Inference Rules (IR) are used, together with Enterprise Modeling (EM) as the canonical modeling language, to deduce dependencies that are not conflicting from dependencies that are or have been identified as an inter-schema property. Three research questions regarding why, how and when IR should be applied in view integration are analyzed and discussed and it is argued that the framework may not only improve view integ...
