A Ruleflow is how Corticon assembles and organizes the components of a set of rules into a single unit. It is a presented as a flow diagram, where Rulesheets, Service Callouts, and even other Ruleflows depict the flow of the rule, allowing it to iterate and to branch.

Once a Ruleflow is defined, it can be tested in Studio, and it can be compiled into a Decision Service for deployment in production environments (as described in the Deployment Guide). 

Important: Corticon's Ruletester lets you test individual Rulesheets as well as Ruleflows in the Studio.  In order to deploy a Rulesheet to it must be part of a Ruleflow. Only Ruleflows can be compiled into Decision Services, and only Decision Services are deployable to Corticon Server .

The Rulesheets components and the Ruleflow must be all using the same Vocabulary file. Ruleflow files have the extension .erf.
