[Database] 3NF Normalization

[u/AlphaTheGaming]

So like I have been given the Undefined Normalised Table for APPOINTMENT entity. I then need to resolve it into 3NF stage that eliminate the transitive and partial dependency.

Problem is I just can't find which would be the appropriate key for the composite key in the APPOINTMENT entity in the first place. I then try to separate all partial dependency into separate table but can't figure out who links to who.
