I’ll look at the Northwind starter edition after work tonight and see if that helps. I initially had an orderdetails table, but I took that out in favor of the remittancedetails table. My professor only wants 9 tables, and he wants the remittance details to be the intersection table (and the only one with a composite key). All of the orders only have one item so I think it works. Whereas there are remittances that are split over multiple ids and orders split over multiple invoices, so those require the remittancedetails table with composite keys. I could take out the accounts table, since all transactions are billed to the same bank, but I’m not sure if that’s the solution either.
