I have a basic question here but I would like to know the best way to structure this.
I have a Customer data type and an Invoice data type. Each invoice will have only one customer, each customer can have multiple invoices.
Is it best to have a List of Invoices field in the Customer data type or have a Customer field in the Invoice data type?
Experimenting with it I can pull the report data (customers - all invoices) both ways but I want to structure the app for the least resistance in the future.
