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 elements of mathematics, statistics, computer science, domain knowledge, and data visualization to uncover patterns, trends, and relationships in data and make actionable decisions.
