13.  Class diagrams also contain information regarding the relationship between them ◦ Association ◦ Dependency ◦ Generalization

14.  Association: A link indicating that two classes need to communicate with one another StudentProfessor

15.  Association: A link indicating that two classes need to communicate with one another ◦ Multiplicity: Every professor has 1 or more students StudentProfessor [1…*]

16.  Association: A link indicating that two classes need to communicate with one another ◦ Multiplicity: Every professor has 1 or more students ◦ Role Names: Students learn from Professors StudentProfessor learns from teaches

17.  Aggregation: “has a” association. Each part exists outside of the whole  Shown by using an empty diamond Car Wheel Engine

18.  Composition: demonstrates strong ownership, the part cannot exist without the whole and vice versa  Shown by using a filled diamond Person Arm Leg

19.  Dependency relationship: ◦ Is a semantic relationship between classes because the functionality of one depends on the other Calendar addEvent(p: Party) Party

20.  Generalization: connection between a subclass and a superclass People StudentProfessor

21.  Sequence diagrams emphasis the time ordering of messages

22. ◦ Objects create the “object life line”

23.  Messages are shown by a horizontal line between life lines ◦ May include a condition CustomerBank withdraw money

24.  A return message is a response from the object CustomerBank withdraw money money

25.  The end of an object life line is demonstrated by an X Bank
