About Unified Data Classification

Unified Data Classification is a Collibra data classification method on Edge. It is based on data classes that you can configure and fully modify depending on your own needs.

• The Unified Data Classification method is enabled by default for all new environments working on Edge starting from release 2024.02, and for all existing environments from 2024.07. It has replaced the old data classification via Edge and data classification via the Cloud Data Classification Platform. A migration process is available to migrate data from old data classification methods to the Unified Data Classification method. Unified Data Classification is the only supported data classification method.
• The Unified Data Classification method works via Edge and requires specific setup.
  Because the data doesn't leave your organization's network, the automatic data classification process is secure. The samples used during the automatic data classification process are temporarily added to the Edge site cache. They are not transferred to Collibra.
• The method relies on classification rules specified for each data class.
  This means that the classification doesn't rely on machine learning, which makes issues and changes more transparent. Using classification rules also provides high flexibility and allows for customizations.

  Note The method does remember any rejected data class suggestions, meaning the data class will not be suggested again if you have rejected the data class for an asset. Also, once a data classification has been accepted for a column, the data classification won't be automatically updated if you run the data classification process again.

• We deliver optional out-of-the-box data classes.
  This means you decide which out-of-the-box data classes you want to use. It also allows you to adjust the provided data classes to your own needs, such as changing the name or classification rules.
• You can start a separate classification process for a specific asset via a dedicated Classify button.
• Unified Data Classification is also available via REST APIs: Data Classification REST API v2, Data Class Management REST API v1, Data Class Import REST API v1.

  Important The Data Classification REST API v1 ClassificationMatches endpoints are also still valid and can be used by Unified Data Classification. The other endpoints in this API are deprecated.

Tip You can follow a training and watch videos via Collibra University.

Data classification steps

Step	Description
	Register a data source via Edge.
	Synchronize one or more schemas.
	Make sure your environment is set up for Unified Data Classification via Edge
	Configure your data classes in Unified Data Classification.
	Classify the synchronized data. You can do this manually or start the automatic data classification process.
