Visual Active Rule Language

Visual Rule Language for ActiveDatabase

This paper introduces a visual language for active database systems. We present a new approach to database programming based on visual active language that allows us to describe active rules in a graphical way. The resulting visual language can be transformed into a textual one. In addition, an active system can be represented with several diierent graphs showing the interactions of rules and t...

Reporting a User Study on a Visual Editor to Compose Rules in Active Documents

In the last years, researchers are exploring the feasibility of visual language editors in domain-specific domains where their alleged user-friendliness can be exploited to involve end-users in configuring their artifacts. In this chapter, the authors present an experimental user study conducted to validate the hypothesis that adopting a visual language could help prospective end-users of an el...

Runtime verification of programs using rule-based active system

ARML: an active rule mark-up language for heterogeneous active information systems

As the information management paradigm shifts from data management to knowledge management, active rule support for various information services has become a practical approach to add intelligence to the existing information management systems. Various active rule systems have been developed using different rule description languages and, yet, their business logics are not sharable with each ot...

Structural Issues in Active Rule Systems

Active database systems enhance the functionality of traditional databases through the use of active rules or`triggers'. There is little consensus, though, on what components should be included in a rule system. In this paper, the expressive power of some simple active database rule systems is examined and the eeect of choosing diierent features studied. Four important parameters of variation a...
