Endret makslengde for produktnavn fra 30 til 45 tegn.
Gjorde følgende endring i databasen: ALTER TABLE products ALTER COLUMN name TYPE CHARACTER VARYING(45); Lagret samtidig lengden på produktnavnfeltet i Product.name_length istedenfor å hardkode det rundt omkring i formatstrenger og input-sjekker. (\ /) (O.o) (> <) Bunny approves these changes.
