Abstract

sources to answer the query. In such an environment, sources can have various constraints on their contents, which the system can use in query processing and optimization.2 With this in mind, my colleagues and I at the University of California, Irvine’s Raccoon Project looked at how to best describe these constraints so that they can be used to answer queries. We classified various constraints; analyzed their motivations, limitations, and advantages; and looked at how to manipulate them. This research gave us greater insight into how we can utilize constraints more effectively.
