AUTOSAR Multiplicity * means 0 .. n or 1 .. n?
AUTOSAR Multiplicity * means 0 .. n or 1 .. n? That means, does * means the corresponding attribute can be optional also or it is a must attribute?
Solution
The meaning of "*" is 0..n. In this specific case the corresponding association in the UML diagram also shows the multiplicity "*". But in many other case where the multiplicity "*" is shown in the class table, the UML diagram shows 0..*.
