Would be great to get some example for the cardinalities I can use.
Especially because glossary and video tutorial are different. The video tutorial about data view says: An order has to have at least one item, but could be more (glossary = n), but tutorial choses cn. so why?? cn should be none or more, no???
please give me some examples, especially for c, cn and 2, would be great.
Thanx
