چکیده

This paper illustrates a prototype system, called GPRS, supporting the Generalized Production Rules database language (GPR for short). The language GPR integrates, in a unified framework, active rules, which allow the specification of event driven computations on data, and deductive rules, which can be used to derive intentional relations in the style of logic programming. The prototype realizes the operational semantics of GPR, implementing both active and deductive behaviors. The rule-evaluation engine of the system is unique. The data model of reference is object based and the system is implemented on top of an object oriented DBMS. Thus, the GPRS prototype represents a concrete proposal of an advanced DBMS for complex objects that supports both active and deductive styles in rule programming.

Active-U-Datalog: Integrating Active Rules in a Logical Update Language

Deductive database technology represents an important step towards the goal of developing highly-declarative database programming languages. In order to make deductive databases a practical technology, deductive rules have to be extended to provide a dynamic behavior. In particular, current applications require not only a support for updates and transactions but also the ability to automaticall...

Palopoli and Torlone : Generalized Production Rules for Active and Deductive

| We address the problem of providing a homogeneous framework for integrating, in a database environment, active rules, which allow the speciication of actions to be executed whenever certain events take place, and deductive rules, which allow the speciication of deductions in a logic programming style. Actually, it is widely recognized that both kinds of rules enhance the capabilities of datab...

Rules in Database Systems

This paper deals with the principles of rule-based systems in databases and gives an overview of existing approaches. First, we introduce the concept of rules. The application of rule-based systems to databases is categorized. Deductive database systems are introduced as the first extension of classical database management systems. We briefly describe the concept of deductive databases and thei...
