Which statement differentiates batch processing from real-time processing?

• A. Batch processes collect data over a period and process at scheduled times.
• B. Real-time processing stores data until an analytic run.
• C. Batch processing processes data as it arrives.
• D. Real-time processing is only used for backups.

Answer: (A)

Batch processing is all about timing: data is collected over a period and then processed together at scheduled times. This approach is efficient for handling large volumes because it maximizes throughput, but it introduces a delay since results aren’t available until the batch runs. Real-time processing, by contrast, handles data as soon as it arrives (or within a few moments), yielding immediate or near-immediate results and enabling live transactions, monitoring, and alerts. The statement that best differentiates batch from real-time is the one that describes accumulating data over time and processing it on a schedule, because it directly contrasts the delayed, scheduled nature of batch work with the instantaneous nature of real-time work. Other options either describe processing as data arrives (which reflects real-time), imply delaying processing until an analytic run (which isn’t real-time), or claim real-time is only for backups (which isn’t accurate).
