  • Publication number: 20130091184
    Abstract: Embodiments of the invention relate to correlating schema mappings. In one embodiment, a set of schema mappings over a source schema and a target schema are received. Each of the schema mappings is decomposed into a basic schema mapping. A first set and second set of relations re determined for the source schema and the target schema, respectively. Each relation in the first set of relations is paired to at least one relation in the second set of relations. The pairing forms multiple relation pairs between the first set and second of relations in the form of (T, T?), where T is a source portion of a relation pair and T? is a target portion of the relation pair. A set of basic schema mappings is identified that matches the relation pair. Each basic schema mapping is merged into a single schema mapping.
