You are familiar with the TAL Distributors database and its set of 3NF relations. A fictitious company, named ABC, uses a similar database design. As compared to TAL, the ABC database uses the exact same structure for the Orders, OrderLine, and Item tables. However, in place of the Rep and Customer tables (of the TAL database), the ABC Company uses the table structures below:

ABCRep (RepNum, RepLName, RepFName, RepStreet, RepCity, RepState, RepZip, RepSalary)

ABCCustomer (CustNum, CustName, CustStreet, CustCity, CustState, CustZip, CustBalance, CustCreditlimit)

ABCRepCust (RepNum, CustNum, CommissionRate)

For Firm ABC, each of the above relations is in 3NF. What 2 differences must exist in the company policies of Firm ABC as compared to TAL Distributors? Explain your answer. (4 pts.)
