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 Cloud Data Classification Platform, your new data class will be used 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 via Edge.

Prerequisites

• You have configured Automatic Data Classification via the Cloud Data Classification Platform (for Jobserver) or via Edge.
• 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, 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.
