Batch processing assemble transactions into groups for processing while Real-time
processing systems process individual transactions continuously as they occur. Batch
processing requires less resources while real-time processing requires more resources
to process. Batch processing has lag time between when the economic event occurs and
when it is recorded while real-time processing has no time lag. Certain records from
batch processing are processed after the event to avoid operational delays while all
records from real-time processing are processed immediately pertaining to the event.
