[[File:Viewer-UML.png]]

The UML panel shows the UML Classes, properties and their relations. Some remarks are in place to explain the diagram:

* Person, Preferences, Student, Teacher and Project are classes.
* Person has two attributes FirstName and Surname.
* Student is a subclass of Person, drawn as an pointing triangle.
* Preferences is dependent on two other class for its existence, hence the lines pointing towards the other required classes with an arrow.
* Teacher also shows a method Check_2 which shows the Teacher instance should check if the properties for Student and Project exist.
* Additionally the numbers indicate cardinality. For instance: a Teacher is mentor for 1 or more Students, and every Student requires 1 Teacher as mentor.
