A class my inherit features form more than one
superclass. A class with more than one superclass
ist called a join class. This is known as
multiple inheritance.

Step 3 Teacher to Student
Vehicle
The land vehicle and the water vehicle are
overlapping sub-classes of the superclass
vehicle. The overlapping sub-class is indicated
by the solid triangle. They are overlapping
sub-classes due to the fact that some vehicles
can travel both on land and on water. Amphibious
vehicle is the join class of land and water
vehicles as it can travel both on land and on
water. It iherits some features from both the
land vehicle and water vehicle classes. The
hollow triangle indicates disjoint sub-classes.
For example, car and amphibious vehicle are
disjoint sub-classes.

Step 4 Student to Teacher
Ahh! Now I understand... The amphibious vehicle
inherits properties from land as well as water
vehicles and is the join class for super-classes,
land vehicle and water vehicle.
Step 5 6 Teacher to Student
Okay... Let us consider another example, in our
University.
Consider our University wich comprises of
different people. It includes faculty members,
students and tutors. Can you draw an object model
showing the class hierarchy of these different
objects?

Step 8 Teacher to Student
Okay, let us look at the problem in this
way...You are a second year undergraduate
student here in RMITs Computer Science
Department. I am undertaking my Masters degree at
RMIT, which makes me a student, and since I am
teching you I am also a faculty member. Can you
modify your object model to represent this
situation?

Hypertext ist eine Konsequenz aus der
Vorstellungswelt des 20. Jahrhunderts, einer
Vorstellungswelt, die sich an immer größere
Komplexität im Denken und in der Praxis gewöhnen
muß.
