Comparison operators

You define rule conditions by specifying a Vocabulary term in a conditions row and entering a value in a corresponding rule column cell. When you do it, the condition automatically assumes the equality = operator.

For example, when you specify Aircraft.aircraftType in a cell in the Conditions pane and enter 747 in a corresponding rule column cell, you define the condition Aircraft.aircraftType = '747'.

However, as you model rules, you may require different types of operators. When you specify a condition that checks if an attribute value is greater than or less than a certain value—for example, cargo volume > 1000 or cargo weight < 100000—use a comparison operator from the library of rule operators that Corticon provides.

The types of comparison operators that you can use in a condition depend on the data type of the attributes in the condition. For instance, for an Integer data type, you can use operators such as >, <, >=, and <=. To check which operators are applicable for each data type, refer to the Attribute Operators category in the Rule Operators view in Corticon Studio.

You can use a comparison operator in a rule by either:

• Double-clicking the rule column cell, and then entering the operator followed by the value.
• Dragging the operator to the rule column cell, and then entering the operator followed by the value.
