Basic mode: The simplified interface helps you create the rule.
The If part represents the condition. It makes the data
quality rule apply to some data only.
The Then part represents the validation expression. It
is executed if the condition is fulfilled.
The Else part represents the alternative validation
expression. When the condition is not fulfilled, this expression is
executed.
The If and Else parts are
optional.
Advanced mode: Type your rule following the The expression language used in advanced mode. This mode allows you to
create more complex rules using more operators and functions than the basic mode.
