Hi,
Ik have the following tables.
INVOICE: InvNr(PK), CustName, CustId, CustAddress
PRODUCTS_CHOSEN: InvNr(FK), ProductNr(FK), AmountChosen
PRODUCT: ProductNr (PK), ProductName, ProductPrice
In 3NF, do I separate the customer data?
The CustId will give me the same CustName every time but since there are multiple John Johnsons in the world, the CustName will not give the CustId.
