Even more useful is a log of all the changes in the database. This gives you what you want, and it would be automatic for any data you store.

So, keep the Boolean, and use a log.

No? So you have to look at database history to extract information you think is useful?

That's a terrible database design.

It's the basis behind Datomic, if I'm not mistaking.

You can easily search through history. The point is, it is better to do this in the design of the database than in the design of the schema.

So: "No?" -> "Yes!"

		Okay, but for something like SQL this seems like a bad idea.
