[Mark Proctor (JIRA)]

    [ https://issues.jboss.org/browse/JBRULES-46?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12595764#comment-12595764 ] 

Mark Proctor commented on JBRULES-46:
-------------------------------------

I'm not sure what backward chaining has to do with sequential mode? Drools already provides a sequential mode that works similar to other major vendors.

> 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.
