Query language approach based on the deductive object-oriented database paradigm
2000, Information and Software TechnologyCitation Excerpt :Our purpose is to find those factors that facilitate query formulation considerably from the viewpoint of the user. We have developed query languages and techniques for their implementation in terms of which specification related to navigation [14,15] and restructuring [27,28] among data can be removed from the user. Likewise we have shown that in deductive databases complex recursive rule definitions for transitive processing can be replaced by a set of operations intuitive to the user [24,25].
