Yerneni, R. and Li, C. and Garcia-Molina, H. and Ullman, J. (1999) Computing Capabilities of Mediators. In: ACM International Conference on Management of Data (SIGMOD 1999) , June 1-3, 1999, Philadelphia, Pennsylvania.
Existing data-integration systems based on the mediation architecture e mploy a variety of mechanisms to describe the query-processing capabilities of s ources. However, these systems do not compute the capabilities of the mediators based on the capabilities of the sources they integrate. In this paper, we propo se a framework to capture a rich variety of query-processing capabilities of dat a sources and mediators. We present algorithms to compute the set of supported q ueries of a mediator, based on the capability limitations of its sources. Our algorithms take into consideration a variety of query-processing techniques employed by mediators to enhance the set of supported queries.
