$[8$:$10$ AM$]$ Bev ShawPractical $04-$ tips

For all relationships specify:

$-$multiplicity on both ends

$-$navigability on one end and aggregation or composition on the other end

$-$there will be ONE composition association, the others are all aggregation

$-$there will be ONE bi$-$directional association; you do not need to add aggregation or composition to that relationship

$-$add a role name on the navigable end of each relationship. The role name specifies the role that the instance plays in the association. You can use role names such as "myTrip" or "hotelAddress"
