Abstract

A view in object-oriented databases (OODB) corresponds to virtual schema graph with possibly restructured generalization and decomposition hierarchies. We propose a methodology, called MultiView for supporting multiple such view schemata. MultiView represents a simple yet powerful approach achieved by breakingview specification into independent tasks: class derivation, global schema integration, view class selection, and view schema generation. Novel features of MultiView include an object algebra for class customization; an algorithm for the integration of virtual classes into the global schema; a view definition language for view class selection, and the automatic generation of a view class hierarchy. In addition, we present algorithms that verify the closure property of a view and, if found to be incomplete, transform it into a closed. yet minimal, view. Lastly, we introduce the fundamental concept of view independence and show MultiView to be view independent.
