Rule

Rule

A rule represents a concrete case in a decision table. It consists of a concrete if-statement (conditions) and the applicable actions for this case. The rules in a decision table are processed from left to right. A DT must have at least one rule.

In the decision table, the rules (columns) are identified by an "R" followed by a sequential number.

A special rule is the ELSE-rule, which is always satisfied when no other rule was previously satisfied.
