At the moment i practice with SQL Databases and created a simple Python tool to manage Order and Inquiry with a simple GUI for testing.
Now I have a question i didn't found a good solution for:
There are standard values for Products like a price and costs etc. These could vary from Order to Order (volume effects etc.). So i need to save them on a different place.
What is a common way to do that?
Having an extra table for Products used in Orders where i copy all standard values from the Product Database and change them there if the price or anything needs to be changed in an order?
