Types of data processing systems

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.”
Commercial data processing
Commercial data processing “involves a large volume of input data, relatively few computational operations, and a large volume of output.” Accounting programs are the prototypical examples of data processing applications.
Data analysis
“Data analysis is a body of methods that help to describe facts, detect patterns, develop explanations, and test hypotheses.” 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.”
