Which statement best describes batch processing in AIS?

• A. Batch processing updates data continuously as transactions occur.
• B. Batch processing aggregates data over a period and processes data in batches.
• C. Batch processing is the same as real-time processing.
• D. Batch processing eliminates the need for data validation.

Answer: (B)

Batch processing in an AIS means collecting transactions over a period and then processing them together as a group. Data from many transactions is gathered into a batch file and, at a scheduled time (often during off-peak hours), the system runs the processing for the entire batch, updating master records and producing reports. This approach is efficient for handling high volumes when immediate results aren’t required, because it smooths system load and can improve throughput. The trade-off is latency—the results aren’t available until the batch runs. This differs from real-time processing, where each transaction is processed as it happens and data is updated immediately. While data validation can be part of batch processing, it does not eliminate the need for validation; checks are applied to ensure accuracy within the batch as well.
