In actual databases, I can explicitly define which table holds the linked column, e.g., Table A has a foreign key field to Table B. So, if I look directly at Table B by itself, I wouldn't know that it has a relationship with Table A. But that's okay, because Table B isn't supposed to hold that information itself.
But in Airtable, I noticed that when I put a linked field in Table A to Table B, instantly that field also appears in Table B. While that's very useful and helpful to understand the bigger picture of how things are interconnected, now I no longer know which table was the original one that established that relationship.
The purpose that I need to know this is to transform an Airtable base into an SQL database schema, so I need to know the "native" fields of each table. Any tips, or anything I missed?
