A bank branch updates customer account balances only at the end of the day by running all the day's accumulated cheque and deposit entries together as one group. Which data processing method is this?
This is batch processing. Transactions are accumulated during the day and processed together as a group at a scheduled time, here at day end. Real-time processing, in contrast, updates records immediately when each transaction occurs.

Explanation
Collecting transactions over a period and processing them together at a scheduled time is batch processing. Real-time and online transaction processing update records immediately on each transaction, so they do not fit the end-of-day grouped run.
