Historical background

The history of Data Science is a continuum of innovation and discovery, fueled by the increasing amount of data and evolving information technologies.

The future of Data Science looks even more promising, with the potential to further revolutionize the way we understand the world and make data-driven decisions.

Data Science, or data science, has emerged as an interdisciplinary field that combines mathematical, statistical, computer and visualization skills to extract meaningful information from data.

Its roots can be traced back to the 20th century, when mechanical computation and statistical analysis began to play an increasingly important role in the social sciences and the field of scientific research. However, it was with the advent of computers and the huge increase in the amount of data available that Data Science began to flourish.

In the 1960s and 1970s, computer scientists developed algorithms and techniques for data analysis, paving the way for the birth of the concept of "data mining." In the 1980s, advances in computer technology made large-scale data processing possible, ushering in the era of "Big Data."

The use of advanced algorithms, machine learning and artificial intelligence has led to further developments in Data Science, opening up new perspectives and challenges in today's world.

The advent of Big Data has revolutionized the modern concept of Data Science, highlighting the importance of extracting business value through the analysis of large amounts of information. Data Science combines scientific skills, such as statistics, mathematics, and computer science, with managerial skills, focusing on the strategic use of data.

Data science can be applied to different areas of expertise (from Finance to Marketing to Production).

We distinguish its mode of application into 4 categories:

  • descriptive - to increase visibility on past or current events;
  • diagnostic - to investigate the causes of events;
  • predictive - to predict future phenomena through observation of history and predictive models;
  • prescriptive - to obtain suggestions on how to act with respect to future events.
