(Databases) EER design help; distinguishing properties of a single, album, and EP watch

    • Thread Starter

    Hi, I am using Enhanced Entity Relationship concepts for designing a database for a music club. I am using "Release" as a superclass, and then I want Single, Album, and EP as subclasses.

    I need help in distinguishing attributes between those 3 subclasses

    anyone got any ideas?
