A decision table is a rule defining a series of tests performed on property values to allow an automated decision. Decision table are instances of the Rule-Declare-DecisionTable rule type.
Decision tables can capture and present business logic in the form of one or more if... then... else conditions.
You can incorporate decision tables in a flow using the Decision shape in Process Modeler. At runtime, the system evaluates the decision tree using the Property-Map-DecisionTable method and stores the result in a property value.
