To Set Multiplicity for the Association
You want to set the multiplicity for this association. However, by default, these labels are hidden. Use the following steps to display the labels on the association link.
1. Right-click the link between Consortium and ATM and choose Labels > Both End Multiplicities.
The pop-up menu closes and the labels for the link appear.
2. Right-click the small diamond at the upper portion of the aggregation link (near the ATM element) and choose Set Multiplicity.
Note: If you have difficulty making the correct pop-up menu appear, lengthen the aggregate arrow by moving the Consortium element farther away from the ATM element.
3. Select 1..*.
Notice that the lower portion of the link is labeled 1 as shown in the following figure.
