Data Integration — Problems, Approaches, and Perspectives

Data integration is one of the older research fields in the database area and has emerged shortly after database systems were first introduced into the business world. In this paper, we briefly introduce the problem of integration and, based on an architectural perspective, give an overview of approaches to address the integration issue. We discuss the evolution from structural to semantic integration and shortly present our own research in the SIRUP (Semantic Integration Reflecting User-specific semantic Perspectives) approach. Finally, an outlook to challenging areas of future research in the realm of data integration is given.
