Abstract

In the past decade, there has been much research effort dedicated to combine the objectoriented programming paradigm and the logic programming paradigm. Most of this effort sheds light upon the philosophy of multiparadigm programming as a near ideal mental model for a wide class of problem domains. In this paper we propose a scheme for object and logic integration---the OLI scheme. This scheme contributes to the multiparadigm programming philosophy by putting forward a multiparadigm design methodology and describing a multiparadigm programming language. Above all, the OLI scheme integrates the object-oriented and the logic programming paradigms at the design and language levels with a precise and well-balanced interface so that each paradigm shares an equal and cooperating partnership in problem analysis and problem solving. An important property of the OLI language is that programmers can program either in one of the paradigms alone or in a mixed paradigm without sacrificing expressiv...
