PK field & Inheritance

ekekakos
P: 4
Hello,
I want to use inheritance and I have created some tables for a program that I want to use it (see attachment).
What is your opinion? Is it better to use the old way or inheritance?
If I use inheritance, would it be good to use as PK for all table the ID field of LASTUPDATE table who will be the parent table of all?
What is your opinion for all these?

Thanks
