Merge data classes

You can merge two or more data classes via the Data Classification Dashboard. For example, if you have the data classes Email, E-mail and email address, then it is recommended to merge them into the packaged data class Email.

Not only will it keep your data classes list clean, but it will give better results when Collibra performs data classification on ingested data.

Note You cannot merge two or more packaged data classes, but you can merge user-defined data classes in a packaged data class. Packaged data classes appear in the Created By column as System User.
