A Deductive Object-Oriented Database System based on Active Rules∗
This paper describes a Deductive Object-Oriented Database (DOOD) system that is built on top of an active Object-Oriented Database (OODB) system. The system, named DEVICE, uses the primitives of the latter, like active rules, simple and complex events, to integrate deductive and production rules. The integration is based on the emulation of deductive rules by special purpose if-then-else produc...
متن کاملOn Harmonically Combining Active, Object-Oriented, and Deductive Databases
Although there are a number of issues to resolve, active databases, object-oriented databases, and deductive databases can be smoothly integrated. We present the integration challenges, provide a resolution to the issues, and show a way to achieve this integration by describing the active, object-oriented, and deductive features of a model/language called Harmony. Harmony lets us see the integr...
متن کاملDeclarative Semantics for Active Rules
In this paper we analyze declarative deterministic and non-deterministic semantics for active rules. In particular we consider several (partial) stable model semantics, previously defined for deductive rules, such as well-founded, max deterministic, unique total stable model, total stable model, and maximal stable model semantics. The semantics of an active program AP is given by first rewritin...
متن کاملChimera: A Model and Language for Active DOOD Systems
Chimera is a novel database model and language which has been designed as a joint conceptual interface of the IDEA project, a major Euro-pean cooperation initiative aiming at the integration of object-oriented, active and deductive database technology. In this paper, we present a view of the main features of Chimera and discuss the design choices made. The most remarkable characteristic of Chim...
متن کاملA Unified Semantics for Active and Deductive Databases
These two rule-oriented paradigms of databases have been the focus of extensive research and are now coming of age in the commercial DBMS world. However, the systems developed so far support well only one of the two paradigms|thus limiting the eeectiveness of such systems in many applications that require complete integration of both kinds of rules. In this paper, we discuss the technical probl...
