  • Abstract
    In this paper, we address the problem of modeling the constraints of a mediated schema. We argue that, from the point of view of an application that processes the results of queries defined over the mediated schema, the constraints should be modeled as the greatest lower bound of the constraints of the export schemas, after appropriate translation to a common vocabulary. This assures that the application will correctly interpret query results.
