Stateful Rule Engine

At run-time, the rule engine executes rules based on new events and data sources on a continuous basis.

The rule memory is never “reset” (unless by design), so that future events can always be compared to past events. For this reason, the rule engine is described as a stateful rule engine.

If required, the working memory can be cleared and a new set of data asserted for each “transaction,” in which case the engine is operating as a stateless rule engine.
