Big data analysis is often shallow compared to analysis of smaller data sets. In many big data projects, there is no large data analysis happening, but the challenge is the extract, transform, load part of data preprocessing. Big data is a buzzword and a vague term, but at the same time an obsession with entrepreneurs, consultants, scientists and
