Data science , also known as data-driven science , is an interdisciplinary field on scientific methods, processes and systems to extract knowledge or insights from data in various forms, either structured or unstructured,   similar to data mining .
Data science is a “concept to unify statistics, data analysis and their related methods” in order to “understand and analyze actual phenomena” with data.  It employees technical and theories drawn from Many fields dans le broad areas of mathematics , statistics , information science , and computer science , In Particular from the subdomains of machine learning , classification , cluster analysis , data mining , databases , and visualization .
Turing award winner Jim Gray is the fourth paradigm of science ( empirical , theoretical , computational and now data-driven) and asserted that “everything about science is changing because of the impact of information technology” and the deluge data .  
When Harvard Business Review is called “The Sexiest Job of the 21st Century”  the term becomes a buzzword , and is now often applied to business analytics ,  or even arbitrary use of data, or used as a sexed-up Term for statistics.  While many university programs offer a science degree, there exists no consensus on a definition or curriculum.  Because of the current popularity of this term, there are many “advocacy efforts” surrounding it. 
The term “data science” (originally used interchangeably with ” datalogy “) HAS Existed for over thirty years and INITIALLY Was used as a substitute for computer science by Peter Naurin 1960. In 1974 Naur published Concise Survey of Computer Methods , qui freely The use of the term data science in its survey of the data processing methods that are used in a wide range of applications.
In 1996, members of the International Federation of Classification Societies (IFCS) met in Kobe for their biennial conference. Here, for the first time, the term data science is included in the title of the conference (“Data Science, classification, and related methods”),  Chikio Hayashi. 
In November 1997, CF Jeff Wu gave the inaugural lecture entitled “Statistics = Data Science?”  for his appointment to the HC Carver Professorship at the University of Michigan . In this reading, he is a statistical worker with a trilogy of data collection, data modeling and analysis, and decision making. In his conclusion, he initiated the modern, non-computer science, use of the term “data science” and advocated that statistical data scientists.  Later, he presented his lecture entitled “Statistics = Data Science?” PC Mahalanobis Memorial Readings.
In 2001, William S. Cleveland, University of Chicago Press, University of Chicago Press, Chicago, IL, ETATS-UNIS Department of Statistics, “Which was published in Volume 69, No. 1, of the April 2001 edition of the International Statistical Review.  In his report, Cleveland establishes six technical areas which he believed to encompass the field of data science: multidisciplinary investigations, models and methods for data, computing with data, pedagogy, tool evaluation, and theory.
In April 2002 the International Council for Science: Committee on Data for Science and Technology (CODATA)  started the Data Science Journal ,  he publication Focused on issues Such As the description of data systems, Their publication on the internet , Applications and legal issues.  Shortly thereafter, in January 2003, Columbia University began publishing The Journal of Data Science ,  which provides a platform for all data workers to present their views and exchange ideas. The paper was largely devoted to the application of statistical methods and quantitative research. In 2005, The National Science Board published “Long-lived Digital Data Collections:
In the 2012 Harvard Business Review article “Data Scientist: The Sexiest Job of the 21st Century”,  DJ Patil claims to have wedged this term in 2008 with Jeff Hammerbacher to define their jobs at LinkedIn and Facebook, respectively. He is a scientist and a scientist at the University of New York.
In 2013, the IEEE Task Force on Data Science and Advanced Analytics  Was lancé, and the first international conference: IEEE International Conference on Data Science and Advanced Analytics Was lancé in 2014.  In 2014, the American Statistical Association Section On Statistical Learning and Data Mining: The Statistical Analysis and Data Mining: The ASA Data Science Journal.  In 2015, the International Journal on Data Science and Analytics  was launched by Springer to publish original work on data science and big data analytics. In 2013, the first ”
ALTHOUGH use of the term “data science” has exploded in business environments, Many academics and journalists see no distinction entre science data and statistics . Writing in Forbes , Gil Press Argues That data science is a buzzword without a clear definition and simply HAS REPLACED ” business analytics ” in contexts Such As graduate degree programs.  In the question-and-answer section of his keynote address at the Joint Statistical Meetings of the American Statistical Association , noted statistician Nate Silver said, “I think data-scientist is a sexed up term for a statistician …. Statistics is a branch of science.
Data scientists use their data and analytical ability to find and interpret rich data sources; Manage large amounts of data and hardware, software, and bandwidth constraints; Merge data sources; Ensure consistency of datasets; Create visualizations to aid in understanding data; Build mathematical models using the data; And present and communicate the data insights / findings. They are often expected to produce as soon as possible, and the results are as fast as possible. 
“Data Scientist” has become a popular occupation with Harvard Business Review dubbing it “The Sexiest Job of the 21st Century”  and McKinsey & Company projecting a global excess demand of 1.5 million new data scientists.  Universities are offering masters courses in data science.  Shorter private bootcamps are also offering data science certificates including student-paid programs like General Assembly to employ-paid programs like The Data Incubator . 
In the 2010-2011 time frame, data science software has an inflection point where open source software started supplanting proprietary software.  The use of open source software allows modifying and extending the software, and it allows sharing of the resulting algorithms.
