===By application area===
====Scientific data processing====
Scientific data processing "usually involves a great deal of computation (arithmetic and comparison operations) upon a relatively small amount of input data, resulting in a small volume of output." <ref name=Reddy>{{cite book|last=Reddy|first=R.J.|title=Business Data Processing & Computer Applications|year=2004|publisher=A P H Publishing Corporation|___location=New Dehli|isbn=8176486493|page=17|url=https://books.google.com/books?id=FLKoXCts9ssC&lpg=PA17&dq=%22scientific%20data%20processing%22&pg=PA17#v=onepage&q=%22scientific%20data%20processing%22&f=false}}</ref>

====Data analysis====
"[[Data analysis]] is a body of methods that help to describe facts, detect patterns, develop explanations, and test hypotheses."<ref>{{cite web|last=Dartmouth College|title=Introduction: What Is Data Analysis?|url=http://www.dartmouth.edu/~mss/data%20analysis/Volume%20I%20pdf%20/006%20Intro%20%28What%20is%20the%20weal.pdf|accessdate=July 5, 2013}}</ref> For example, data analysis might be used to look at sales and customer data to "identify connections between products to allow for cross selling campaigns."<ref>{{cite book|last1=Berthold|first1=M.R.|last2=Borgelt|first2=C|last3=Hőppner|first3=F.|last4=Klawonn|first4=F|title=Guide to Intelligent Data Analysis|year=2010|publisher=Springer|isbn=978-1-84882-260-3|page=15}}</ref>▼
