Leontiev, Yuri, Ozsu, M. Tamer, Szafron, Duane

Technical report TR98-01. In this paper we present a type system that combines inclusion and parametric polymorphism with behaviors (multi-methods) and precise function typing. Type declarations allow user-definable variance specification of type parameters and user-definable subtyping between...

Peters, Randal J., Ozsu, M. Tamer, Szafron, Duane, Lipka, Anna

Technical report TR93-01. The establishment of a formal object model provides a theoretical foundation to investigate other objectbase features such as query processing. In this report, we present an extensible uniform behavioral object query model for the TIGUKAT(*) object management system. ...

Peters, Randal J., Szafron, Duane, Ozsu, M. Tamer

Technical report TR92-14. Object-oriented computing is influencing many areas of computer science including software engineering, user interfaces, operating systems, programming languages and database systems. The appeal of object-orientation is attributed to its higher levels of abstraction for...
