View Generation and Optimisation in the AutoMed Data Integration Framework

This paper describes view generation and view optimisation in the AutoMed heterogeneous data integration framework. In AutoMed, schema integration is based on the use of reversible schema transformation sequences. We show how views can be generated from such sequences, for global-as-view (GAV), local-as-view (LAV) and GLAV query processing. We also present techniques for optimising these generated views, firstly by optimising the transformation sequences, and secondly by optimising the view definitions generated from them.
