We are gonna draw a DMN diagram for entities like the image below. Travel entities include a list(many to one relation) of Persons. enter image description here

There is a problem with designing a DMN with Enterprise Architecture for such a system: It is not possible to use the data type defined as person in travel and it must be defined in travel. We would like some think like (Person : Person) but as far as I know we haven’t got complex type in EA.

enter image description here

enter image description here

After all we can’t add list data in dataset dialog

  • A `Person` is a `Travel`? Can I live where you live? – qwerty_so Mar 30 '21 at 15:59
  • @qwerty_so Look at the diagram! I think so he/she wanted to show Travel has got many persons. Please focus on the main problem, how we can add a list of persons in travel object. – Ghanat Mar 31 '21 at 04:14
  • I'm not in DMN so I can't contribute. The above is a funny observation. You need a laugh from time to time. Just use your cheek muscles :-/ – qwerty_so Mar 31 '21 at 10:19
