$$ An INVOICE is written by a SALESREP. Each sales representative can write many invoices,

but each invoice is written by a single sales representative.

$$ The INVOICE is written for a single CUSTOMER. However, each customer can have many

invoices.

$$ An INVOICE can include many detail lines $($LINE$),$ each of which describes one product

bought by the customer.

$$ The product information is stored in a PRODUCT entity.

$$ The product$$s vendor information is found in a VENDOR entity.
