Big data has evolved from being used to describe a large dataset with 3 Vs: high volume, high velocity and high variety, to a field that can analyze complex datasets, both structured and unstructured, for insights that lead to better decision making capabilities in scientific and business worlds. This roadmap assumes you already have access to XSEDE computational and storage resources and know how to use them. XSEDE users can assess their knowledge of big data using the Big Data badges.
