Here is a question about maintaining a personal ledger in an SQL database. It seems to have been closed because it was about programming.
In my opinion, this is a valid question about personal bookkeeping, not programming. The core question is: which data should the asker "write down" in his ledger in order to account for changing exchange rates?
The fact that it's an SQL database is merely background information. The exact same question would also apply to a pen-and-paper ledger.
But the question is closed, and apparently, I'm "delusional" (see comments) for thinking this is an accounting question rather than a programming question.
Should this have been closed?
