Two types of indicators are listed under the Indicators folder in the DQ Repository tree view of the Profiling perspective: system indicators and user-defined indicators.

User-defined indicators, as their name indicates, are indicators created by the user. You can use them through a simple drag-and-drop operation from the User Defined Indicators folder in the tree view. User-defined indicators are used only with column analyses. For more information on how to set user-defined indicators for columns, see Setting user-defined indicators from the analysis editor.

System indicators are predefined indicators grouped under different categories in the System Indicators folder in the DQ Repository tree view. Each category of the system indicators is used with a corresponding analysis type.

You can not create a system indicator or drag it directly from the DQ Repository tree view to an analysis. However, you can open and modify the parameters of a system indicator to adapt it to a specific database for example. For further information, see Editing a system indicator.

Only system indicators you can modify are listed under the System Indicators folder in the DQ Repository tree view. However, the Indicator Selection dialog box lists all indicators including the system indicators you can not modify, such as Date pattern frequency.

Several management options including editing, duplicating, importing and exporting are possible for system and user-defined indicators. For more information, see Managing user-defined indicators and Managing system indicators.

The following sections to follow describe the system indicators used only on column analyses. These system indicators can range from simple or advanced statistics to text strings analysis, including summary data and statistical distributions of records.
