Validates data using data quality rules from:

  • Talend Cloud Data Stewardship, or
  • The hybrid version of Talend Data Stewardship 8.0 R2022-07 or greater.

A data quality rule is a set of business requirements which defines the values your data must comply with.

To retrieve the data quality rules into a JAR file, tDataQualityRules lets Talend Studio connect to Talend Cloud Data Stewardship or the hybrid version of Talend Data Stewardship. Talend Studio uses the retrieved library so you can apply data quality rules to your data. For more information on how the component works, see tDataQualityRules local and Cloud/hybrid process.

The component returns the data into categories and subcategories:
  • Valid:
    • Valid: The data fulfill the condition and the validation expression or the data fulfill the alternative validation expression only.
    • Not applicable (NA): The data do not fulfill the condition. The rule cannot be applied to the data.

    These data follow the Main flow.

  • Invalid:
    • Invalid: The data fulfill the condition but not the validation expression.
    • Not executable (NE): The rule cannot be executed on the data.

    These data follow the Reject flow.

This component is not shipped with your Talend Studio by default. You need to install it using the Feature Manager. For more information, see Installing features using the Feature Manager.
