B.Tech in Data Science in India is an undergraduate engineering degree designed to develop strong foundations in mathematics, programming, databases, and computer science, along with specialized training in data analytics, machine learning, and big data systems. The curriculum typically begins with engineering fundamentals such as calculus, linear algebra, probability, data structures, and object-oriented programming, and gradually advances to statistical learning, data mining, deep learning, cloud computing, and distributed processing. Students learn to collect, clean, store, and analyze large datasets using tools like Python/R, SQL, Hadoop/Spark, and visualization platforms, while also studying model evaluation, MLOps basics, and responsible AI. Most institutes include labs, mini-projects, internships, and a final-year capstone project that mirrors industry workflows like building end-to-end pipelines and deploying models. The program is suitable for students interested in engineering roles that combine software development with analytics and AI, and it supports careers in IT services, product companies, BFSI, e-commerce, healthcare, manufacturing, and consulting.
