Temporal reasoning and processes
Business rules allow us to define smarter processes depending on the contextual informa-
tion we feed the rule execution engine. The combination of rules and processes is a very
powerful mix that provides a way of merging specific sequence of actions with reactive be-
havior in a very performant way. It is now time to start learning about involving temporal
information inside our rules definitions.
Adding temporal information such as fact time correlation, streams of data, or any live data
will add a lot of power to your rule executions and their capacity to infer information from
the real world. These procedures are encompassed in
complex event processing
(
CEP
), a
methodology to infer complex situations out of simple ones, and
Event-driven Architec-
ture
(
EDA
), which allows for a natural growth of applications that use CEP. We will see
each of these concepts in detail.
