Updating Datalog databases,problem: i) the formalization of a declarative, model-theoretic semantics of insertions (and, dually, of deletions), with potential, minimal, and deterministic results; ii) an operational, proof-theoretic approach, that turns out to be equivalent to the declarative one.

,Declarative languages — Paradigm of the past or challenge of the future?,sirable and can be achieved without suffering from the drawbacks encountered when simply combining existing query and programming languages. In this paper we outline the basic design decisions of an experimental language aimed at a knowledge-based style of persistent programming.

An object-oriented data model for artificial intelligence applications, of the paper the syntax and formal semantics of . are introduced; then the rules to compute subsumption between types are defined. Finally it is shown that subsumption for . is sound and complete; furthermore, we prove that . is tractable though it results to be more expressive than ., the tractable form of ..

The LOGIDATA+ model and language,s: classes, relations and functions. LOGIDATA+ databases can be accessed by means of a rule-based language, a typed extension of logic programming languages with specific constructs to refer to classes, functions, and relations.

A glimpse of paradise,tures..With these basic ideas in mind, we shall propose and sketch a specific design for a language and lay out some explicit requirements. Doing so, we shall try to compare this attempt to the state of the art.

Typing schemes for objects with locality,of an object is part of its static type specification and the predefined reachability constraint is enforced via a static typing discipline. We conclude by highlighting the impact of locality information on the operational support to be expected by next generation database systems.
