| Abstract | Exchanging and integrating data that uses different vocabularies are two prominent problems in the database literature. These problems have been, so far, solved separately, and never been addressed together in a unified setting. In this paper, we propose a class of mappings - called DSE, for data sharing and exchange - that represents this unified setting. We introduce a DSE setting with particular interpretation of related data where ordinary data exchange or data integration cannot be applied. We define the class of DSE solutions in a DSE setting, that allow to store a part of explicit data and a set of inference rules used to generate the complete set of exchanged data. We identify among those a particular DSE solution with good properties; namely, one that contains a minimal amount of explicit data. Finally, we define the set of certain answers to conjunctive queries. |
