Data Science involves different subjects such as data mining, data statistics, data analysis, and data visualization. Collating vast data sets and managing them for specific purposes is the basic process, but there is a need to upgrade since technology continues to advance constantly.

The data science method has been used for a long time, even before it was given the term. The term â€śdata scienceâ€ť was first introduced in 1974 by Peter Naur. He proposed the name as an alternative term for computer science. The topic, however, was featured specifically in a conference at the International Federation of Classification in 1996.

The evolution of modern data science took a long journey to what it is now. Keep reading to learn its rich history and the long journey it took over the decades.
