My name is Don, so every time I see a column called "createdon" I think it's a boolean flag that you can set true to create me. I wish the db designer would use snake case instead of mashing all the words together. But then again, I keep my ssh key in a file called donkey.pem.

The "big-endian naming mould" suggests naming it orders_per_month_max, since orders is the object (most significant), per_month is a count of orders (secondary significance), and max is a constraint of the order per month count (least significant).

Then you can use other parallel names in the same big-endian pattern, like orders_per_month orders_per_year orders_per_year_max orders_per_second_min refunds_per_year_average etc, and they will all sort next to their closely related names, instead of the "inline max" or "prefix max" scrambling the alphabetical order.
