How to use native data type as a field in drupal 7?

Question

I have several user data types in drupal 7

• a restaurant
• menu
• recipe
• cook

I want to create associations between this data collector → restaurant → menu → recipe so that the recipe can get the name of the cooks and the address of the restaurants and the menu can get a list of recipes, etc.

In the SQL country, I would call it a foreign key, but I have a lot of problems finding how to do this in drupal 7.

I suspect there must be some kind of module or functionality that I am not familiar with. But drupal uses its own jargon, and I think I'm falling for my google-fu

Does anyone know what I'm looking for?
