Hello, my question is somewhat similar to the question in practice paper. If I draw the CD as shown above, will my corresponding OD still match? Or does my OD violate some rules of the CD. Since the multiplicity is not stated, can we assume that it can take on any values, including zero?

Yes, I believe it is compliant.

Personally, I think since the multiplicity is not stated, it could be any numbers, including 0.

In this case, in the object diagram, we can interpretate as the chair object has 0 table object and table object has 0 chair object. Therefore, it is compliant.

Might be wrong tho.

Technically, not enough information to decide (because the multiplicity is not given)
