A retail supermarket processes daily customer sales using a computerized record system. In what sequence should the following operations occur during a standard transaction cycle?
- 1Scanning product barcodes at the point-of-sale checkout counter
- 2Computing totals and updating inventory balances in the database
- 3Printing a detailed paper receipt for the customer
- 4Backing up updated ledger files to a remote cloud server
Cevap
The correct logical sequence is: Scanning product barcodes at the point-of-sale checkout counter → Computing totals and updating inventory balances in the database → Printing a detailed paper receipt for the customer → Backing up updated ledger files to a remote cloud server.
The standard electronic data processing cycle follows four main sequential stages: Data Input (scanning product barcodes), Data Processing (calculating totals and updating inventory records), Information Output (printing customer receipts), and Data Storage/Backup (archiving updated business records to secure cloud storage).
