On sabbatical leave from Stony Brook University. 1 Introduction In recent years, several papers [BANC90, BEEC88, CLUE89, DLR88, KS90, 1] have proposed query languages for object oriented databases. However, none of these languages captures (or even attempts to deal) with all the aspects of the object oriented model. In this paper, we present a new query language that incorporates features not found in earlier languages. The ....

Rather, we use the familiar SQL like syntax to illustrate certain philosophy in designing object oriented languages a philosophy put forward in [KIM89b, KS90] and [CW89, KW89, KW92, KLW90] Before discussing the novelties found in our language, we should point out some of the differences between the object oriented model and the relational model. The different features of these two models induce different modes of representing information and querying ....
