Batch processing
Technique of processing data that occur in one large group instead of individually. Batch processing is usually done to help conserve system resources and allow for any modifications before being processed. For example, a banks will batch process all their transactions once every hour instead of processing each transaction immediately. Another example, is the Microsoft Outlook e-mail program, which will keep all your e-mails in an Outbox that is processed every few minutes. This allows for an e-mail to be edited or deleted before it is sent.
