Which description accurately contrasts batch processing with online real-time processing?

• A. Batch processing processes each transaction as it occurs.
• B. Online real-time processing aggregates transactions for periodic processing.
• C. Batch processing aggregates transactions for periodic processing.
• D. Batch processing makes data available instantly for decision makers.

Answer: (C)

Batch processing works by collecting transactions over a period, grouping them into a batch, and then processing the entire group at scheduled times. This approach is efficient for handling large volumes when immediate results aren’t needed, and it often runs during off-peak hours to update systems and produce reports in one go. That’s why describing batch processing as aggregating transactions for periodic processing is the best fit. Processing each transaction as it occurs describes online real-time processing, not batch, because real-time systems update outputs immediately with every transaction. The idea of online real-time processing aggregating for periodic processing is inconsistent. Saying data is available instantly for decision makers also describes real-time systems, not batch.
