Using queues: Example
When you want to divide the verifying and optimizing work among multiple workstations, one way is to use queues.
Assume you want certain Verify operators to process invoices from certain suppliers. After each invoice is scanned or interpreted, you can add it to a queue according to the supplier. Invoices for supplier names starting with A through D could go into queue 1, suppliers E through G into queue 2, and so on.
The Verify operators can run jobs that process invoices from "their" queues.
