Need help to create a DB

Recommended Posts

Hi :)

I need help to create a DB, I have a piping table and am wondering if I can create one  table only or is suitable to create more than one, as you can see in the picture.

What i want to do is in the second picture.

That's a lot of numbers. Can any of them be calculated? Is there a formula for anything?
