How do I save a database tag?
- The easiest way: create a tag table, create an entity table, create a many-to-many table like { tag_id, entity_id }. For every tag/entity insert that pair into link table.

To add or modify tags for existing database clusters, use the cluster’s More menu and select Edit tags. On a project’s dashboard, you can also hover over an untagged database cluster’s row of information to reveal the Add tags link. No matter which way you navigate, the Manage Tags dialog opens.
