My names Justin King, I'm a part of a research project at Swinburne
University of Technology in Melbourne, Australia. my question is in
regards to the new Drools and more specifically fusion. I'm having
trouble determining whether Fusion might fulfill a requirement of our
project so maybe you can help me out. Essentially we are in need of an
Event Condition Action (ECA) engine. We wish to be able to define
trigger the firings of certain rules based on an event occurring inside
our system, e.g. a timer going off. Any sets of rules listening for
this event should evaluate their 'when' conditions and execute their
'then' actions. So essentially its something like:<br>
<br>
Event: Timer expires<br>
Rule: rule 1<br>
<br>
Event Timer expires<br>
Rule: rule 3<br>
<br>
So rule 1 and 3 have now 'subscribed' to the timer event. so rule 1
might be something like <br>
<br>
CONDITION 'if students have not finished their exam' <br>
ACTION 'fail students'<br>
<br>
Does drools fusion allow for this type of ECA pattern, or is it a
different form on engine.<br>

Drools Fusion can do this. It allows you to look at conditions over
time and aggregations over time, and reason over them.<br>
