[jboss-jira] [JBoss JIRA] Updated: (JBRULES-46) Prolog Style Query Based Backward Chaining

Prolog Style Query Based Backward Chaining ------------------------------------------ Key: JBRULES-46 URL: https://jira.jboss.org/jira/browse/JBRULES-46 Project: Drools Issue Type: Feature Request Security Level: Public(Everyone can see) Reporter: Mark Proctor Assignee: Mark Proctor Forward Chaining means that facts are asserted and propgated forward throughout the network, during forward propagation matching takes place which results in rules being fired - the rules are event based, in that they are fired in response to changed in the working memory. Backward chaining is query based. Rules attempt to fire first but do not have the necessary matched facts, so facts are pulled in from an external source.
