Earlier quoted context omitted.
I'm curious about this. I thought double entry book-keeping was mostly an artefact of manual/analog book-keeping. Humans are notoriously error-prone, and it's easier to avoid errors when two sets of numbers are supposed to balance out (ideally, exactly). How is double entry beneficial once all transactions are documented digitally? Could you give a somewhat concrete example? (Contrived or otherwise)?
Double-entry refers to the number of accounts related to a transaction, rather than the process of entering it twice. When you think about it, all transactions have naturally (at least) a from and a to account. In the simplest example, I move $100 from one checking account to another. This is a pain to model in a spreadsheet, where I literally create two entries, but very easy to model in an electronic dual-entry sys…
Hm. I guess I didn't know there was such a thing as single-entry :-)
Thank you for clarifying, that makes sense. We actually had a (little too much, or too little) about this in high-school. But it looked a lot more like: https://en.wikipedia.org/wiki/Double-entry_bookkeeping_syste... (debit and credit "accounts").
It struck me as odd to keep the term when handling it somewhat differently (although also somewhat similarly).
I suppose the term is old enough that it covers both "double meta-data" and "double(redundant/check-summed) storage".
