Repetition of Information

1. Our decomposition does not suffer from the repetition of information problem.
   • Branch and loan data are separated into distinct relations.
   • Thus we do not have to repeat branch data for each loan.
   • If a single loan is made to several customers, we do not have to repeat the loan amount for each customer.
   • This lack of redundancy is obviously desirable.
   • We will see how this may be achieved through the use of normal forms.
