In data integration, a Merge operator takes as input a pair of schemas in some conceptual modelling language, together with a set of correspondences between their constructs, and produces as an output a single integrated schema. In this paper we present a new approach to implementing the Merge operator that improves upon previous work by considering a wider range of correspondences between schema constructs and defining a generic and formal framework for the generation of schema transformations. This is used as a basis for deriving transformations over high level models. The approach is demonstrated in this paper to generate transformations for ER and relational models.
