Maritime Big Data De? ned
Example of big data displayed in graphs by suing Kyma software.
“Big data is a term that describes large volumes of high velocity, complex and variable data that require advanced tech- nique sand technologies to enable the capture, storage, distribution, manage- ment, and analysis of the information.” (Tech America Foundation’s Federal Big Data Commission, 2012).
