is only part of the key, thus the same value<br />
of OfficeID occurs with different values of the<br />
other part of the key, i.e., ClientID.<br />

A057 1111 BS32<br />
A908 1234 MN08<br />
B123 1111 SB01<br />
B123 2222 SB01<br />
B123 3333 SB01<br />
Then, the relationship between AcctNumber and<br />
OfficeID has to be repeated, which is redundant.<br />
