Abstract

The need for accessing independently developed database systems using a unified or multiple global view(s) has been well recognised. This paper addresses the problem of redundancy of object retrieval in a multidatabase setting. We present the materialisation rules we have used for supporting data integration in a heterogeneous database environment. The materialisation rules are capable of directing the global query processor to combine data from different databases. Also, these rules are able to reconcile database heterogeneity that may be found due to independent database design.
