Operators

An operator is a mathematical function that defines the outcome of a condition. Select an operator determines whether the results of the condition analysis pass to the action in the rule statement.
The following table describes the operators that you can select:
Operator
Description
is
Tests whether the input data matches the data that the condition specifies.
is not
Tests whether the input data does not match the data that the condition specifies.
is within
Tests whether the input data matches a value in a set of values.
Select the operator when you use a reference table in the condition.
is not within
Tests whether the input data does not match a value in a set of values.
Select the operator when you use a reference table in the condition.
is less than
Tests whether the input data value is less than the value that the condition specifies. Select the operator with numeric input data.
is less than or equal to
Tests whether the input data value is less than or equal to the value that the condition specifies. Select the operator with numeric input data.
is greater than
Tests whether the input data value is greater than the value that the condition specifies. Select the operator with numeric input data.
is greater than or equal to
Tests whether the input data value is greater than or equal to the value that the condition specifies. Select the operator with numeric input data.
You can define the same condition in multiple rule statements. Use different operators to specify different actions. For example, you define a condition to analyze an input column of date data. You want to specify different actions if the input data indicates an age greater than 18 or lower than 18.
You configure the following rule statements:
IF AGE >= 18 THEN ADULT
IF AGE < 18 THEN CHILD
The rule statements use the same inputs and conditions. The operators determine the actions that the rule statement can take.
