Need advice on mysql normalization and php class structure?

Put it all in one table and have a media_type column.

Make it one table with an extra column "media_type". Your design would require you to make an extra table for every new media type and that is possibly poor design.

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.
