Martín,
>Say the clerk at the front updated the customer city and the one on the back updated the zip code, or in a more typical case, Alice updates the customer Region and Bob updates its Salesperson. Now, both updates are sent to DB, and you get a zip which don't match the city, or a Region not matching the SalesPerson.
Shame on you Martín. You should normilize your database! <s>
