začať sa učiť
zero or one
multiplicity of association, what does 1...* mean?
začať sa učiť
at least one
what are Interaction Diagrams?
začať sa učiť
Formalized description and notation of dynamic behaviour and collaboration of group of objects
interaction diagrams what are objects involved called?
začať sa učiť
participating objects
give 1 example of an interaction diagram
začať sa učiť
Sequence diagrams
what is a state chart diagram?
začať sa učiť
The dynamic of a system can be described with a number of states and the transitions between them
What is a state?
začať sa učiť
