== Data science ==
'''Data science''' is an interdisciplinary field that uses scientific methods, algorithms, processes, and systems to extract knowledge and insights from structured and unstructured data. It combines aspects of statistics, computer science, and domain-specific knowledge. Data science is closely related to [[data mining]], [[machine learning]], and [[big data]].

== History ==
The term "data science" has been in use since the 1960s but gained prominence in the early 21st century. In 2001, William S. Cleveland proposed data science as an extension of statistics. The field expanded with the rise of [[big data]] technologies and the increased availability of computational power. The phrase "data scientist" was popularized by companies like [[Google]] and [[LinkedIn]] in the 2010s, and a 2012 [https://hbr.org/2012/10/data-scientist-the-sexiest-job-of-the-21st-century Harvard Business Review article] called it "the sexiest job of the 21st century".

== Methods and techniques ==
Data science involves several stages: data collection, cleaning, exploration, modeling, and interpretation. Common techniques include [[regression analysis]], [[clustering]], [[neural networks]], and [[natural language processing]]. Tools such as [[Python (programming language)|Python]] and [[R (programming language)|R]] are widely used, along with frameworks like [[Apache Hadoop]] and [[Apache Spark]] for scalable processing.

== Applications ==
Data science is applied in many fields, including [[healthcare]], [[finance]], [[marketing]], and [[social media analysis]]. For example, [[recommender systems]] use data science to suggest products or content, and [[fraud detection]] algorithms rely on pattern recognition from historical data.
