How may batch processing be used to improve operational efficiency?

What will be an ideal response?

A single transaction may affect several different accounts. Some of these accounts, however, may not need to be updated in real-time. In fact, the task of doing so takes time which, when multiplied by hundreds or thousands of transactions, can cause significant processing delays. Batch processing of non-critical accounts, however, improves operational efficiency by eliminating unnecessary activities at critical points in the process.
