Update Sensitive Data Models
There are many reasons why you may need to update a sensitive data model after you discover sensitive columns on your target database. Perhaps changes on the database have occurred or you may need to fine-tune the discovery results. With Data Discovery, you can perform incremental discoveries and make manual changes to your sensitive data model.
You can also manually edit the XML version of a sensitive data model in a text editor. To obtain an XML format of your sensitive data model, you need to generate it first and then download it from the sensitive data model's page. See Download or Upload a Sensitive Data Model in XML Format.
Perform an Incremental Discovery of Sensitive Data on Your Target Database
If columns are added, deleted, or modified on your target database after you run a data discovery job, you can perform an incremental discovery to update your sensitive data model. This operation compares the sensitive columns in your sensitive data model to those on the target database and informs you of the differences. If needed, you can adjust the schemas and sensitive types that Data Discovery uses during the incremental discovery on the target database.
View the History of Incremental Discovery
Data Discovery maintains a history of each incremental discovery job on a sensitive data model (SDM). For each job, you can view when the incremental discovery was performed, the selected schemas for the incremental discovery, the selected sensitive types, what column changes were approved or rejected, and whether the changes were applied to the SDM.
Add New Sensitive Columns to a Sensitive Data Model
You can add new sensitive columns to an existing sensitive data model on the sensitive data model's page.
Add Previously Removed Columns to a Sensitive Data Model
You can view the list of previously removed columns from a sensitive data model (SDM) and add those columns back to the SDM as needed.
Remove Sensitive Columns from a Sensitive Data Model
Sometimes Data Discovery returns columns that you do not want to include in your sensitive data model. You can remove them from the sensitive data model on the sensitive data model's page.

Add or Remove a Referential Relationship from a Sensitive Data Model
You can add or remove a referential relationship between two database columns in your sensitive data model.
Referential relationships are leveraged in operations such as masking. During masking, the relationship helps ensure the integrity and consistency of the masking format applied. Relationships can also potentially be leveraged during incremental discovery using the sensitive data model (or manual column addition to the sensitive data model) to pull in other related columns.
