Help with class diagram associations

Hi everyone

I’ve got a project and I need some help with the associations between classes. Aggregations, compositions, … I don’t understand much of that.

Check it out and give me your opinion please.

Thanks,

Chiapa

While I don’t understand the language, here is my interpretation of the diagram:

I see no aggregations or compositions modelled here.

Hope that helps.
