  1. Online real-time processingAnswer
  2. B
    Batch processing
  3. C
    Deferred processing
  4. D
    Commercial service processing

Answer

Online real-time processing is the method where data is entered and records are updated immediately upon transaction occurrence.
Online real-time processing captures data at the exact moment a transaction occurs (such as scanning barcodes upon arrival) and immediately updates the system records so that current stock levels are reflected without delay.

Step-by-Step Solution

1
Analyze the operational scenario
Goods are scanned and stock records update instantaneously at the point of entry.
Immediate update of master files upon input defines real-time processing.
2
Distinguish between data processing modes
Instant updates contrast with batch processing (delayed group updates) and deferred processing.
Selecting the option corresponding to instant database update accurately identifies online real-time processing.
