Rol : a Deductive Object - Oriented Database System
نویسندگان
چکیده
ROL is a deductive object-oriented database system developed at the University of Regina. It supports important object-oriented features such as object identity, complex objects, classes, class hierarchies, multiple inheritance with overriding and blocking, and schema deenition. It also supports structured values such as functor objects and sets, providing powerful mechanisms for representing both partial and complete information about sets. It provides a uniform declarative language for deening, manipulating and querying databases. This paper describes the structure and operation of ROL.

متن کاملTowards a Uniform Deductive Object-Oriented Database Language
Deductive object-oriented databases are intended to integrate the deductive and object-oriented database techniques to combine the best of two approaches and to overcome their inherent shortcomings, with a number of deductive object-oriented database languages proposed. However, most of these languages are only structurally object-oriented. Important behaviorally object-oriented features such a...
