Evaluation Aspects of a Object-Oriented Deductive Database Language
Georg Lausen, Beate Marx · MADOC (University of Mannheim) · 1992
Recently, F-logic has been proposed as an attempt to extend deductive databases by typical concepts of object-oriented languages. Among these concepts are complex objects, (term-based) object identity, methods, classes, typing, inheritance and browsing. In Kifer et al. syntax and model-theoretic semantics is discussed; however many algorithmic aspects which arise when computing the corresponding models are left open. In this paper we start to bridge this gap. Several topics in the context of the evaluation of programs are discussed in detail; among these are weak recursion, global stratification and dynamic type-checking.
