Abstract: This book aims to provide a foundational layer of computing technology for master's students in applied statistics specializing in big data analysis. Developed within a collaborative innovation platform involving five universities, the book focuses on the core technical competencies required for big data analysis and integrates three major compotents: operating systems, programming languages, and databases. Throug the Python toolchain, it offers end-to-end training in data acquisition, processing, and visualization, while platforms such as MySQL strengthen data management skills. Emphasizing the integrationm of theory and practice, the book includes applied case studies designed to support teaching in statistical analysis and big data technologies.
