Towards a Deductive Object-Oriented Database Language

Towards 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...

Approaches to deductive object-oriented databases

This paper is concerned with the problem of combining deductive and object-oriented features to produce a deductive object-oriented database system which is comparable to those currently available under the relational view of data modelling not only in its functionality but also in the techniques employed in its construction and use. Under this assumption, we highlight the kinds of issues that ...

ROL2: Towards a Real Deductive Object-Oriented Database Language

A Typed Deductive and Object - Oriented Database LanguageMengchi

This paper presents a novel typed deductive object-oriented database language, called ROL (Rule-based Object Language), which is being developed at the University of Regana. This language is a declarative language. It can naturally and directly support object-oriented features such as object identity, complex objects, classes, class hierarchy, multiple inheritance with overriding, and schema in...

ROL : A DEDUCTIVE OBJECT BASE LANGUAGEyMengchi

| This paper presents a novel deductive object-oriented database language, called ROL (Rule-based Object Language), which is being developed at the University of Regina. ROL eeectively integrates important features of object-oriented databases and deductive databases into a uniform framework. It supports object identity, complex objects, classes, class hierarchy, multiple inheritance with overr...

Query language approach based on the deductive object-oriented database paradigm

The integration of data-oriented (structural), behavioral and deductive aspects is necessary in next generation information systems. Therefore the deductive object-oriented database paradigm offers a very promising starting point for the implementation of these kinds of information systems. So far in the context of this paradigm a big problem has been the lack of a query language suitable to an...
