Figure 2-4
This illustration describes how data labels and user labels work together
by showing two users attempting to access four labeled data rows. User
1 has a label HS:FIN:WR that allows her access to data row 2 (HS:FIN:WR_SAL),
data row 3 (U:FIN), and data row 4 (C:FIN:WR_SAL). User 2
has a data label S:FIN:WR_SAL that allows him to access data row
3 (U:FIN) and data row 4 (C:FIN:WR_SAL).
