+ "What's the difference?\n",
+ "\n",
+ "**Batch processing** is when data processing and analysis happens on
a set of data that have already been stored over a period of time. In other
words, the input is a finite, bounded data set. An example is payroll and
billing systems that have to be processed weekly or monthly.\n",
+ "\n",
+ "**Stream processing** happens *as* data flows through a system. This
results in analysis and reporting of events within a short period of time or
near real-time on an infinite, unbounded data set. An example would be fraud
detection or intrusion detection.\n",
Review Comment:
Check my above comment. I think here is more for users who do not have any
data processing background.
