Active Database Manifesto

   Posted by: dhcsoul   in Complex Event Processing

Your first time here? Welcome, I'm glad you've dropped in.... David Soul (aka Bricoleur)

In contrast to traditional database systems active database systems management are designed to automatically react to events.

Typically they use either of two mechanisms:

    1. periodically poll the database
    2. embed or encode event detection and related action execution in the application code.

The rules that govern the operation are
typically formulated as Event-Condition-Action (ECA) where occurence of
various types of events (e.g. dtabase transitions, time events,
external signals) trigger the evaluation of a condition and if and only
if the condition evaluates to true, the action is carried out.

The Active Database Systems Manifesto: A rulebase of ADBMS Features”  edited by Klaus R. Dittrich, Stella Gatziu, Andreas Geppert (Institut fur Informatik, Universitat Zurich, Switzerland)
is an attempt to clarify the notion of this type of system.  The
editors distinquish mandatory features as well as desirable features.
