In order to have a more complete class hierarchy, we must take into account
that a university has not only employees, but students as well. To add this,
refer to the Workstudy View (new
window), which shows the attributes in the Student relational base
table. From this, the Entry Date can be factored up into a Student Class as
shown below. This introduces multiple inheritance to this object schema where
the Workstudy class inherits attributes from both Teacher and Student. You
should note that not all programming languages can support multiple inheritance.
Nevertheless, it is important to understand the concept.
Yes, there are still redundant attributes in the Student and Employee
classes. They will be addressed in the next step.
