When you build a rule to configure the scorecard, the Profile Statistics panel extracts and displays the corresponding entity's column statistics. You can analyze the statistics for an entity's column rule and make decisions to build a better rule for your entity. The statistics are auto-refreshed based on your column selection in the Rule Builder.
Note: The statistics displayed on the panel are non-editable. It is intended for viewable purposes only.
The Profile Statistics panel allows you to:
  1. Select a column name from the Column drop-down to view the statistics of any particular entity's column.
    Note: The profile statistics for Service Configuration Output Fields will not be displayed.
  2. View the detailed profiling statistics of an entity by clicking on Details adjacent to the Column drop-down. If you click on Details, you are navigated to the Data Profiling Results page with the details of the corresponding column. For more information, see Viewing Data Profiling Results.
    Note: The Profile Statistics panel is available only if you had run the profile against the selected entity. In case your selected entity has never been profiled, you must run the profile against the entity at least once to make the Profile Statistics panel visible, or configure and run the scorecard once to make the statistics available during the rule update, but in this case, you will not see the Details link to view the detailed profiling statistics.
The Profile Statistics panel displays these comprehensive profiling statistics of an entity generated at the column level:
  1. Completeness: Displays the completeness of records in the column. The percentage of Complete, Null, and Empty String detected in the column are displayed in the legend.
  2. Uniqueness: Displays the uniqueness of the data contained in the column by showing the percentage of these statistics in the legend:
    • Unique: Records with no duplicates in the data source.
    • NonUnique: Records having duplicates in the data source.
    • Distinct: A list of all records present in your data source irrespective of those being unique or non-unique record.
  3. Frequency: Displays the frequency of the data contained in the column.
    Note: It is displayed only if the column data type is string.
  4. Patterns: Displays the pattern of the data contained in the column.
    Note: It is displayed only if the column data type is string.
