Using RELATIONAL DATABASES in Notion (Easily ) | Notion Tutorial

For someone who knows relation databases this explanation is confusing. What are equivalents of unique keys, foreign keys, attributes, etc. Is there a logic in relationships or u just relate everything chaotically they way u see fit.

Some time my relationships work, some them donʼt, even if they worked yesterday.

Thank you man appreciate the great non-BS video

dope tutorials brother

Do you set up the databases first, then relate them? I sometimes don't know what I need until I start creating inside of Notion. But that doesn't always work. I think I need to plan the databases needed first, then work them. If that makes sense!

Thanks
