I am trying to find the reason how the 15 points are taken off from my class diagram.
I have two questions,
1. do we need to point out the direction(bi or uni) for association or it is not important?
2. If I want to draw the relation for robot, parts, handpart, footpart, bodypart, headpart.
robot and parts should be aggregation or composition relationship?
3. manage session bean and entity bean should be dependency or association relationship?
Thanks.
