Create a user-defined data class

If the Automatic Data Classification process cannot detect a data class for a column, you can classify the column yourself.

• If you are using the Data Classification Platform, your new data class will be sent to the Data Classification Platform to improve its future predictive capabilities.
• If you are using Edge, the user-defined classes are only stored. You can use them to manually assign the data class to a column. The user-defined classes are not used to retrain the classification model. See About profiling and classification via Edge.

Prerequisites

• You have configured Automatic Data Classification for the DGC service.
• You have the correct permissions to classify tables and columns.
• You have registered a data source via Jobserver or via Edge.
  When you use Jobserver, ensure to:
  
  • Store Data Profile.
  • Store Sample Data. The more sample data, the better the data class predictions.
  Note For Jobserver to improve Automatic Data Classification, all sample data and profiling data is stored in the Collibra cloud repository.
• Data Catalog experience is enabled in the DGC service configuration.
  This will give you access to the improved Schema asset page.

Create a user-defined data class via the Table asset page

1. Find the table that contains the columns to classify.
2. At the bottom of the Columns section, click See all.
3. If not yet available, add the Data Classification column to the table.
4. In the Data Classification column of the row that you want to classify, click .
5. Click the Select field.
   The list with existing data classes appears.
6. In the Select field, enter the new data class name and press Enter.
   Note 

   • Data classes are case-sensitive and can contain spaces.
   • You can add more data classes if applicable but avoid it as much as possible.
7. Press Escape and click .
   The new data class is automatically accepted.

Create a user-defined data class via the Column asset page

1. Find the column you want to classify.
2. In the tab pane, click Data Profiling.
3. In the Data classification section, click .
4. Enter the new data class name and press Enter.
   Note 

   • Data classes are case-sensitive and can contain spaces.
   • You can add more data classes if applicable but avoid it as much as possible.
5. Click Save.
