    schema:text "Null with a business meaning: card.daily_atm_limit_amount uses NULL to mean no limit, while account_overdraft_terms.overdraft_limit_amount uses NULL to mean not yet decided; the same null means two different things and an unlimited card cannot be told from one whose limit is unknown (BR-309). Fixed by stating unlimited explicitly (an indicator or a limit type, with a check that the amount is null exactly when unlimited) and keeping NULL for unknown only. Replacing NULL with a large number scores 0."@en .
