That sounds like a 1:many relationship. But your table structure feels like a many:many relationship. Which is it?

You show 3 tables, each with very few fields; are there other fields in those tables? If not, I would question the split of the tables. For example, having an extra table just for the "deleted" flag seems excessive.

Perhaps I could better understand things if you showed some sample data. It should exemplify the 1:many and many:many relationships. It should be obfuscated if necessary (to hide sensitive data).
