In this paper, we discuss the use of ontologies for data integration.We consider two different settings depending on the system architecture: central and peer-to-peer data integration.Within those settings, we discuss five different cases studies that illustrate the use of ontologies in metadata representation, in global conceptualization, in high-level querying, in declarative mediation, and in mapping support.Each case study is described in detail and accompanied by examples.
