Master Data Services (MDS) is removed in SQL Server 2025 (17.x). We continue to support MDS in SQL Server 2022 (16.x) and earlier versions.
In Master Data Services, you can use change tracking groups to take action when an attribute value changes. Use change tracking when you don't know what the new value will be, but instead want to know if any change occurred.
Configuring Change Tracking
To configure change tracking, you add an attribute to a change tracking group. The group can contain one or many attributes. Then, you create a business rule to define the action that is taken when any of the attributes in the group change.
Note
Change tracking business rules consider staged (imported) data to be changed.
