Hi! I need some help please!
I have to create a DB that has to be normalized to 3NF. I have a table 'Products' that contains info about all the products -
quanitity (left in warehouse),
And I have TWO more tables that contain info about transactions - 'Procured products' and 'Sold_products' tables.
In both these tables I have a field with number of procured and sold products.
My question is - is it possible or do i have to link the product_quantity in warehouse with the quantity of procured_products and the sold_products so my DB would meet 3NF?
