Help on relational schema

jungleroomxjungleroomx Never pre-order anything.Registered User regular
So im good, except my prof seems to be making shit up on the fly. Ive looked through all course material and nowhere does it show how to work on what I guess is a multi-valued relationship.34pq0foob8sg.jpg

Im lost. There is nothing anywhere on what this is, or what it takes to solve them. Could anyone help?

    Nevermind. He made a mistake.

    You're referring to the double-lined relationship, yes?

    That is a thing, but not in this example. A double-lined attribute means multi-value, but a double-lined entity or relationship means a weak entity or relationship to a weak entity.
