Question

PostgreSQL

Good afternoon, there is a question of implementing several levels of the referral program, more precisely 15 levels

. How to correctly determine which level a user belongs to and how to store it all correctly in BD postgres

with level 1 is easier, but how to determine level 2, etc.?

Answer 1
