Delete individual data parts

In this article, you will learn how to delete specific data parts (also referred to as records) from a golden record. For more information about records, data parts, and golden records, see Data life cycle.

If you no longer need specific data parts that form a golden record, you can easily delete them. You can delete data parts from a golden record in two places:

  • On the History tab – use this option if you want to have a detailed and chronological view of all data parts forming a golden record. For more details, see History.

  • On the Topology tab – use this option if you want to have a visual representation of how a golden record is formed.

Deleting data parts from a golden record is different from removing records from a data source. When you remove records from a data source, all data parts originating from that source are removed from every golden record in which they are used. On the contrary, deleting data parts from a golden record allows you to delete specific data parts originating from almost any source. In this case, the data parts are deleted only from the specific golden record.

Deleting data parts from either the History tab or the Topology tab produces the same result: the data part is removed from the golden record. However, there are several cases when you cannot delete data parts from a golden record. A data part cannot be deleted from a golden record under the following conditions:

  • If it is the only data part that contains the origin code of the golden record.

  • If it is a manual merge data part. You can undo the manual merge on the Topology tab.

  • If it is a deduplication project merge data part. You can undo the deduplication project merge on the Topology tab.

  • If it is one of two data parts that contribute to the merge data part.

Even though you can delete a data part from an enricher, keep in mind that it may appear again. To prevent this, deactivate the related enricher before deleting a data part.

    The data part is removed from the History tab. Consequently, all changes that the data part contributed to the golden record are also removed.

Delete data parts in Topology

On the Topology tab of a golden record, you view how the data parts forming a golden record are linked. If you don’t need a specific data part in a golden record, you can delete it.

To delete data parts on the Topology pane

  1. Find and select the data part that you want to delete.

  2. In the data part details pane that opens, select Delete.

  3. Review the data part that will be deleted, and then select Next.

  4. Confirm that you want to delete the data part by entering DELETE. Then, select Confirm.
