    I think this is the first video I've ever seen that has no dislikes and thousands of views. Well done.

    You cleary have a great understanding, you're able to explain a confusing definition quite simply. I really need my lecturer to watch your videos.
    Much appreciated Caleb!

    Caleb, great videos and awesome explanation. I hope you can clarify your example a bit. You made a great analogy with the percent share column that has its place in the association table. Here's the question: would any other normalization/dependency be broken if say 60% share was present in 2 or more rows? Wouldn't the attribute "percent_share" describe multiple entities formed by user ID+listing ID comp key? The reason I ask is because at the beginning of the video you made another example of dependencies using ID entity and email attribute, where multiple IDs couldn't have same email. Thank you very much!

    I don't understand the point of ussing a composite key. Seems easier to just add a column with auto increment - there, unique id for every row...
