Object - Oriented Approach for Managing

A large scaled network may consist of hundreds of disparate and autonomous databases. Users in such an information-providing environment usually access information from those databases in the same or similar application domains so that there is no need to handle all the entities from all the databases. That is, in most cases, only a subset of databases is required for the users' requests. As the number of databases increases, the need to manage such a network of databases increases. In this paper, we present a split/cluster approach using the object-oriented technique to allow users to incrementally and dynamically access the information they want without being overwhelmed with all of the unstructured information. The approach is based on the aanity relationships of the databases and is performed recursively to split these databases into clusters. Then a cluster hierarchy is formed to provide diierent levels of abstractions for the users. This framework provides a exible means of sharing information to all the databases. Theoretical terms along with a running example are presented.
