Abstract

An important task of multidatabase systems is the integration of existing databases. Database integration is achieved primarily through the use of generalization. Hence, it is important to develop good tactics for processing queries over generalization hierarchies. This paper defines the class of conjunctive generalization queries, and it describes four tactics for processing those queries that have boon developed for the MULTIBASE system. Since query processing tactics are best describe algebraically, the paper shows how to model generalization as a sequence of algebraic operations. Three of the tactics described here are adapted from convontional distributed query processing techniques. However, it is argued that these tactics are of limited applicability to processing queries over generalization hierarchies. A fourth tactic, semiouterjoin, which is more widely applicable, is introduced.
