The correct answer is: A. Batch processing
Batch processing is a type of data processing where transactions are accumulated into groups (batches) and processed at a scheduled time. This is in contrast to real-time processing, where transactions are processed as they occur.
Batch processing is often used for tasks that are not time-critical, such as payroll processing or inventory management. It can also be used to process large amounts of data, such as credit card transactions or customer orders.
Batch processing has several advantages, including:
- It can be more efficient than real-time processing, as it allows for the processing of large amounts of data at once.
- It can be less expensive than real-time processing, as it does not require the same level of hardware and software resources.
- It can be more reliable than real-time processing, as it is less susceptible to errors.
However, batch processing also has some disadvantages, including:
- It can be slower than real-time processing, as it requires the accumulation of data into batches before it can be processed.
- It can be less flexible than real-time processing, as it is not as easy to make changes to the data or the processing schedule.
- It can be less secure than real-time processing, as it is more difficult to monitor and control the data.
In the case of the daily processing of corrections to customer accounts, batch processing is the most appropriate option. This is because the processing of these corrections is not time-critical, and it can be done more efficiently and cost-effectively in batches. Additionally, batch processing is more reliable than real-time processing, which is important for ensuring that customer accounts are accurate.
The other options are not as appropriate for the daily processing of corrections to customer accounts. Real-time processing would be too slow and expensive, and it would not be as reliable as batch processing. Time-sharing would not be appropriate because it is designed for multiple users to access the same data at the same time. Offline processing would not be appropriate because it does not allow for the real-time processing of data.
