Hmmm.. I think I need your advice here to get in correct direction...

I am almost ready with my learning project in PHP/MySQL.
I can register new product in stock.
Add and increase the number and weight.
I can move products between different storehouses
I can also transfer products from store and onto a "truck document" but
that's it and here I need some advice.

I like to register new products and the amount in number (for example 4)
and weight in kg.

I like to write it in this way:
Dynamite - package 4 - Weight 200 kg
Lunt - Package 10
