30.5. "Add an Attribute column"

With this column option, you can add one or more attribute columns representing any of the DRL rule attributes, such as Saliance, Enabled, Date-Effective, and others.

For example, the following guided decision table uses the salience attribute to specify rule priority and the enabled attribute to enable or disable rules for evaluation. Rules with a higher salience value are evaluated first, and rules with the enabled attribute are evaluated only if the check box is selected.

図30.5 Example rules with salience and enabled attributes to define evaluation behavior

rule "Row 1 Pricing loans"
  salience 100
  enabled true
  when
    ...
  then
    ...
end
...
rule "Row 3 Pricing loans"
  enabled false
  when
    ...
  then
    ...
end

For descriptions of each attribute, select the attribute from the list in the wizard.
