-# Associations
-
-An Association classifies a set of tuples representing links between typed instances, e.g., two instances of classes at runtime.
-
-### Example
-

-
-# Aggregation and Composition
-
-Aggregation and Composition are subsets of associations, i.e., they are specific cases of association.
-In both aggregation and composition object of one class "owns" object of another class. But there is a small difference.
-
-## Aggregation
-
-Aggregation implies a relationship where the child can exist independently of the parent.
-
-### Example
-
-![Aggregation Class Diagram](https://git.informatik.uni-kiel.de/ag-se/teaching-public/-/wikis/uml-sources/img/aggregation.png)
-
-Lecture (parent) and Student (child). Delete the Lecture and the Students still exist.
-
-## Composition
-
-Composition implies a relationship where the child cannot exist independent of the parent.
-
-### Example
-
-![Composition Association Class Diagram](https://git.informatik.uni-kiel.de/ag-se/teaching-public/-/wikis/uml-sources/img/composition.png)
-
-Person (parent) and Head, Leg, and Heart (children). The children don't exist separate to a Person.
