Data science is an interdisciplinary field that utilizes scientific methods, processes, algorithms, and systems to extract knowledge and insights from structured and unstructured data. Data scientists apply advanced analytical techniques to make sense of large volumes of data, enabling organizations to make data-driven decisions. Here's an overview of typical subjects, courses, and syllabi you might encounter in a data science curriculum:
