sorry but are you really an "expert"? do you really have a master's or a doctorate? because it's very weird to answer off the mark each time honestly, it's level L2
Solution incorrect. CEO is not an entity and you missed GreenChampion
Hello,
If GreenChampion is not an entity, why someone told me this ?
Thank you
Hello,
Can you tell me if for this exercise, there are 6 or 7 entities? and if, tell me why? Because someone told me that GreenChampion is an entity but I'm not sure about that.
I wanted to know also, why we don't connect carbon transaction with product with the verb "recorded" since the sentence said that : 'Optionally, the single product that the carbon transaction relates to can also be recorded'.
Thank you.
Sorry but I don't understand your explication. in the solution, you say that CEO is an entity and now you say the opposite? I do not understand??
Je ne vois rien à propos du GreenChampion.
I don't understand why CEO is an entity? For me, we link company to employee by the relation "composed" and composed has a CEO name which is an attribute of the relation.
And why there is nothing about GreenChampion?
Hello, why on the diagram there are no associations or cardinalities?
