The correct answer is D. All of the above.
A DASD (Direct Access Storage Device) is a type of storage device that allows for direct access to data, without having to go through a sequential process. This makes it ideal for storing data that needs to be accessed quickly, such as pending invoices.
If payment execution is batch, then the pending invoice file will need to be accessed frequently in order to process payments. If invoice data entry is one-line, then the pending invoice file will need to be accessed frequently in order to enter new invoices. And if inquiries concerning payable are to be answered on-line, then the pending invoice file will need to be accessed frequently in order to answer those inquiries.
Therefore, the pending invoice file should be stored on a DASD if any of the above conditions are met.
Here is a more detailed explanation of each option:
- Option A: Payment execution is batch. This means that payments are processed in batches, at regular intervals. In order to process payments, the pending invoice file must be accessed to retrieve the invoices that need to be paid. If the pending invoice file is stored on a DASD, then it can be accessed quickly and easily, which will help to speed up the payment process.
- Option B: Invoice data entry is one-line. This means that invoices are entered into the system one line at a time. In order to enter an invoice, the pending invoice file must be accessed to retrieve the invoice template. If the pending invoice file is stored on a DASD, then it can be accessed quickly and easily, which will help to speed up the invoice entry process.
- Option C: Inquiries concerning payable are to be answered on-line. This means that inquiries about invoices, such as the status of an invoice or the amount due, are answered immediately. In order to answer an inquiry, the pending invoice file must be accessed to retrieve the invoice information. If the pending invoice file is stored on a DASD, then it can be accessed quickly and easily, which will help to speed up the inquiry response process.
