Ivar Hagen, Mikael Berndtsson, Sharma Chakravarthy, Brian Lings · 1998
In this paper we present lessons learned from an implementation of a task shared cooperation protocol using event-condition-action (ECA) rules in the active database ACOOD. In particular we present details of challenges for ECA rule designers when supporting advanced forms of coordination protocols. Keywords: Active databases, coordination protocols, task sharing. 1 Introduction We belive that applications developed within the frameworks of Cooperative Information Systems [14] and Cooperative Information Agents [15] will have to deal with techniques from both distributed artificial intelligence (DAI) and database management systems. The need for DAI techniques is apparent in many different areas today. One typical system is the automation of an office environment. Such an environment usually consists of several problem solving agents (PSAs) with specialized talents to solve a particular kinds of problem. The PSAs can be either humans or computing systems. Obviously there are many com...
