I notice that Smith_Customers has full address1/2, City/State/Zip for each customer but the table and Billing Address (but not as Line 1 and 2) and Billing Zip does not  contains columns for billing City or Billing state. The page populates them from the customer address fields. The full billing info is stored in Smith_PayHist. I was just wondering what the underlying reasons were that the billing address and zip is captured in the Customer record but not the billing address 2, billing city or billing state?  It seems sort of unusual that the customer would have to enter the 3 fields (Billing Address 2, Billing City and Billing State) each order if they were different from the customer fields. Thank you.
