A logistics company combines structured delivery records held in databases with unstructured customer emails, GPS feeds and photographs of damaged parcels. Which of the five Vs is most directly illustrated by the mix of data formats?
The answer is variety. Variety refers to the differing forms of data, such as structured database records alongside unstructured emails, GPS feeds and photographs. Volume concerns quantity, velocity concerns speed, and value concerns the usefulness of the insights gained, so they do not describe a mix of formats.
