Yea I agree with you - if your database only ever has one concurrent user (one app and one person using that app at a time) then it doesn't matter that much how you implement it, either in the DB or in the app. The benefit of doing it in the DB is that multiple apps or people using the same data concurrently can be easier to manage depending on the situation. But if it's a single user app? Whatever you prefer is probably fine.
