Summary: Data exchange is a field of database theory that deals with transferring data between differently structured databases, with motivation coming from industry [21,17]. The starting point of intensive investigation of the problem of data exchange was given in [14] where it was defined as, given data structured under a source schema and a mapping specifying how it should be translated to a target schema, to transform the source data into data structured under the target schema such that it accurately reflects the source data w.r.t. the mapping. This problem has been studied for different combinations of languages used to specify the source and target schema, and the mappings [8]. Most of the results in the literature consider tuple generating dependencies (tgds) as the language to specify mappings. Tgds allow one to express containment of conjunctive queries, and have been widely employed in other areas of database theory. Furthermore, once a target instance is materialized, one mightwant to perform query answering over it.
