What is data science?
Data Science is rooted in the extraction of insights from raw and unstructured data. Today's organizations handle vast amounts of structured and unstructured data regularly. The term "Data Science" was coined in the early 1960s to describe a new profession that aimed to interpret the massive amounts of data being accumulated at that time. Utilizing computer science and statistical methodology, Data Science has evolved as a discipline to generate valuable predictions and insights in a diverse range of fields. The rapid pace of technological advancement and the increasing digitization of information have made Data Science a highly popular field.
