Hi Armin!

Yes, it is correct. CzescZlozona has chirdlen :
"czesciAtomowe" field (1:n) (in real world it would be similar to workers)
and one of this chirdlen is special instance, marked as
("glownaAtomowa" field, 1:1) (in real world - i.e. - chief)
> If your mapping is correct, does CzescAtomowa has any references?
