Rule Engine

This section describes several components, functionalities, and operations of the Business Rule engine. The rule engine provides the execution context for a rule set. The RuleEngine object uses the following plug–in components for implementation:

• Ruleset executor (inference engine). Implements the algorithm responsible for rule condition evaluation and action execution. The default rule set executor is a discrimination network-based forward-chaining inference engine designed to optimize in-memory operation.

• Ruleset translator. Takes as input a RuleSet object and produces an executable representation of the rule set. The default in-memory translator creates a compiled discrimination network from the rule set definition.

• Rule set tracking interceptor. Receives output from the rule set executor (inference engine) and forwards it to rule set tracking and monitoring tools.
