System indicators are predefined but editable indicators that you can use on analyses. For more information on the system indicators available in the studio, see Indicator types.

How to edit a system indicator

Although system indicators are predefined indicators, you can open their editors to check or to edit their settings and their definitions in order to adapt them to a specific database version or to a specific need, for example. However, you can not edit the name of the system indicator.

Prerequisite(s): You have selected the Profiling perspective in the studio.

To edit a system indicator, do the following:

  1. In the DQ Repository tree view, expand Libraries > Indicators, and then browse through the indicator lists to reach the indicator you want to modify.

  2. Right-click the indicator name and select Open from the contextual menu.

    The indicator editor opens displaying the selected indicator parameters.

  3. Modify the indicator metadata.

    You can edit any metadata field of the system indicator except the indicator name which is not editable..

  4. Click Indicator Definition.

    In this view, you can edit the indicator definition, change the selected database and add other indicators specific to available databases using the [+] button at the bottom of the editor.

  5. Click the save icon on top of the editor to save your changes.

Note

If the indicator is simple enough to be used in all databases, select Default in the database list.

Warning

When you edit an indicator, you modify the indicator listed in the DQ Repository tree view. Make sure that your modifications are suitable for all analyses that may be using the modified indicator.

How to set system indicators and indicator options to column analyses

You can define system indicators and indicator parameters for columns of database tables that need to be analyzed or monitored. For more information, see How to set indicators on columns and How to set options for system or user-defined indicators.

How to export or import system indicators

You can export system indicators to folders or archive files and import them again in the studio on the condition that the export and import operations are done in compatible versions of the Studio. For further information, see Exporting data profiling items and Importing data profiling items or projects.

How to duplicate a system indicator

To avoid creating a system indicator from scratch, you can duplicate an existing one in the indicator list. once the copy is created, you can work around its metadata to have a new indicator and use it in data profiling analyses.

Prerequisite(s): You have selected the Profiling perspective in the studio.

To duplicate a system indicator, do the following:

  1. In the DQ Repository tree view, expand Libraries > Indicators.

  2. Browse through the indicator lists to reach the indicator you want to duplicate, right-click its name and select Duplicate... from the contextual menu.

    The duplicated indicator is displayed under the System folder in the DQ Repository tree view.

You can now open the duplicated indicator to modify its metadata and definition as needed. For more information on editing system indicators, see How to edit a system indicator.
