Two modes are available to create a rule:
  • 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 Data Shaping Expression Language . This mode allows you to create more complex rules using more operators and functions than the basic mode.

To create a data quality rule, you must log in as a rule manager. For more information about the roles, see Managing the roles.
