question for relationship in class diagram

[mikeh Chang]

Hi my friends,

I have the following question for class diagram.

Is it correct to change the relationship's multiplicity in the class diagram?

eg. In the BDM, the equipment(Airplane) and Flight's relationship is 1:1.
In my class diagram, I want to change it to 1:n.
Can I change it?

Hi Mikeh,
I have seen people passing the exam after changing the BDM. And that means sun is not very stringent about the relationships in the model. So you are free to change it the way you want. But the most important thing is you will have to justify in your document WHY you changed it.

Hi, Giju,

BDM refers to business domain model. Domain models describe
business processes. These processes are documented as a sequence of
actions that provide observable value to a business actor.

For a good understanding of BDM's, refer to the following link :
