Welcome to the Data Science section. This discipline combines many fields, often even conceptually very different from each other, including statistics, data analysis, data mining, machine learning and Big Data.
Data Scientists, on the other hand, are people who study and deal with data science, and are a rapidly growing professional figure in the last decade. This profession requires a wide range of skills to analyze data collected from the web, smartphones, customers, sensors and other sources. It is therefore a lot for them, to stay updated every day, always up to date in a rapidly developing discipline.
