After you create a tag, you can associate the tag with one or more objects. You can also remove the association between a tag and an object. You can use the tag to search the domain for objects associated with the tag. The Developer tool displays a glossary of all tags.

For example, you create a tag named XYZCorp_CustomerOrders and assign it to tables that contain information for the customer orders from the XYZ Corporation. Users can search by the XYZCorp_CustomerOrders tag to identify the tables associated with the tag.

When you deploy a mapping that is associated with a tag, the tag is propagated to the run-time version of the mapping on the Data Integration Service. If you update the deployed mapping using an application patch, the name of the patch is associated as a tag with the run-time version of the mapping.
