ODDI : a framework for semi-automatic data integration
Recent works on Business Intelligence do highlight the need of on-time, trustable and sound data access systems.
Moreover the application of these systems in a flexible and dynamic environment requires for an approach based on automatic procedures that can provide reliable results.
A crucial factor for any automatic data integration system is the matching process.
Different categories of matching operators carry different semantics. For this reason combining them in a single algorithm is a non trivial process that have to take into account a variety of options.
This paper proposes a solution based on a categorization of matching operators that allow to group similar attributes on a semantic rich form. This way we define all the information need in order to create a mapping. Then Mapping Generation is activated only on those set of elements that can be queried without violating any integrity constraints on data
