Several data management tasks require to precisely establish associations between data structured under different schemas. Schema mappings allow the definition of semantic connections between schemas with structural differences. A schema mapping M is a specification of a relation between instances of a source schema S and instances of a target schema T. Given a source instance I for S and a target instance J for T, they satisfy the mapping if (IJ)⊧M. Schema mappings are used both for virtual and materialized integration, and they have been studied in many aspects, including their specification, semantics, and user-assisted generation.
