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