History Of Data Science:

The phenomena of Data Science have evolved over the years to become what we today understand Data Science to be. It was first brought to notice in 1962 when John Tukey wrote about merging Statistics and computers to obtain measurable outputs in lesser time. Peter Naur, in 1974, used the term “Data Science” in his review “Concise Survey of Computer Methods.”

This was followed by linking modern computer technology, traditional statistical methodology, and domain expertise to convert data into knowledge by International Association for Statistical Computing (IASC) 1977. Later in 2001, William S. Cleveland presented an activity plan that depicted the understanding and scope of Data Scientists.

In 2002, the “Data Science Journal” was published by International Council for Science. This journal focused on several related issues like data systems explanation, applications, etc. This was followed by several other Data science journals by Columbia University in 2003 and National Science Board in 2005. By 2013, Data Science became a leading field of study that was increasingly adopted by businesses.
