According to various trade journals and corporate marketing machines, we are now on the verge of a revolution| the object-relational database revolution. Since we b e l i e v e that no one should face a revolution without appropriate armaments, this paper presents BUCKY, a new benchmark for object-relational database systems. BUCKY is a queryoriented benchmark that tests many of the key features offered by object-relational systems, including row t ypes and inheritance, references and path expressions, sets of atomic values and of references, methods and late binding, and user-de ned abstract data types and their methods. To test the maturity of object-relational technology relative t o relational technology, w e provide both an object-relational version of BUCKY and a relational equivalent thereof (i.e., a relational BUCKY simulation). Finally, we brie y discuss the initial performance results and lessons that resulted from applying BUCKY to one of the early object-relational database system products.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
