7:17 inclusive subtype is antipattern. Supertype can ONLY have ONE subtype. David C. Hay talks about this in "Data modeling patterns" ~30 years ago.

Thanks I was designing a database for a project (Music App) and was confused whether I should keep all users in same table or use this concept of entity subtype to store additional info about a role in a separate table
