Topic 04, Part 11 - Supertype and Subtype Entities

Dr. Soper discusses supertype and subtype entities and how they can be used to model "is-a" relationships in entity-relationship diagrams. This video is Part 11 of Topic 04 in Dr. Soper's class on Database Design and Management.

This explanation was fantastic! It was clear, concise, and made a potentially confusing topic incredibly simple to understand. I really appreciate the effort you put into making this video. Thank you so much!

Perfect, clear and straight to the point. Very insightful.

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
