Association End Navigability
IsNavigable specifies in which direction(s) an association between two classes can be traversed. To avoid crowding the drawing, this is only indicated when only one direction is possible.
Example of navigability:
• It is important to be able to find out what products are contained in an order.
• However, it is rarely useful to be able to find all orders that concern a product.
Specifying navigability for a role
To indicate that an association is navigable in one direction only:
1. Right-click the non-navigable role.
2. Select IsNavigable > No.
An arrow representing the navigability now appears for the other role.
