Abstract:
In an environment consisting of a large number of databases, it can no longer be reasonable to assume that construction of users ' views could rely on an a-priori static partial or global schema integration. Approaches which are based on integrated mechanisms are obviously intractable (if not impossible) within a large size environment. In this paper, we propose an approach where users are allowed to dynamically investigate information and incrementally specify their views. The idea is to use a functional approach to model the construction of views. Further, our approach provides a mechanism by which views adapt to the evolution of the information space. This mechanism relies on dynamic triggers to fulfill this goal. 1.
