Data science is an interdisciplinary field that uses scientific methods, processes, algorithms, and systems to extract knowledge and insights from structured and unstructured data, combining statistics, computer science, and domain expertise.
Key skills include programming (Python, R), statistics, machine learning, data visualization, database management (SQL), and strong communication for explaining insights and findings.
Data analytics primarily focuses on describing past events ('what happened?'). Data science extends beyond this to predictive modeling ('what will happen?') and prescriptive actions ('what should we do?'), often involving more complex algorithms.
Data scientists are employed across nearly all sectors, including technology, finance, healthcare, retail, marketing, entertainment, and government, due to the universal need for data-driven insights.
