The biggest added value of the EDA infrastructure is the concept of event-processing
agents. When they generate complex events from different sources, they usually do it by
using a complex event-processing framework, such as the Drools rule engine to handle
different stream of events and define filters and conditions.
We can leverage the power of an event-processing agent to influence our business pro-
cess's execution, create new process instances based on the aggregation and correlation of
events that come from different sources, or even notify external applications or users
about the completion of a business process under a set of specific circumstances. In
Drools rule engine (and particularly a set of APIs called Drools Fusion) to integrate com-
plex event-processing features with our BPM systems.
In the next figure, we see a combination of process engine and event-processing agents
from the perspective of a particular process; combined, they can model very complex
business scenarios.
