Abstract
This work presents a schema evolution methodology able to propagate structural and semantic modifications occurring in the local schemas of a federated database to the integrated schema. Our approach is to regard this problem from a schema integration point of view. Our theoretical framework is based on a declarative schema integration methodology, which reduces schema integration to the resolution of a set of equivalence correspondences between arbitrarily complex local subschemas.
