Normalization and Unique Ids?

Having or not having surrogate ID's for something has nothing to do with normalization.

You could use project_id and video_url as a function dependency key in your model but at a physical level I would not like to use a URL as part of a key.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
