I've got a case where a surrogate key is added for uniqueness to an entity that references few other entities and I believe it is a good candidate for the Dependent Child Key / Link structure, this entity is however referenced by yet few more granular entities so as result I would use the same Dependent Child Key in more than one link. I'm wondering if this is ok or would it not be according to good practices?
