I would say you can expand that on the following criteria: 1) a lot of people can have read access, but only a few should have write access, and read access should be restricted to specific tables without PII. 2) The people with write access should go through a Change Approval process: they submit the SQL they're going to run and someone else approves or denies it before it can be done. 3) Every piece of SQL that modifies a table should be annotated with a comment and the ticket number in it in which that change was approved. 4) You should be able to rollback any committed change within an hour of it happening.
