The main subjects of the big data major are as follows:

Data Science and Big Data Technology (Science Degree), in the case of Peking University, the main courses include: probability theory, mathematical statistics, applied multivariate statistical analysis, functions of a real variable, applied regression analysis, Bayesian theory and algorithms.

Applied Time Series Analysis, Statistical Computing, Statistical Machine Learning, Programming Internship, Data Structures and Algorithms, Distributed and Parallel Computing, Algorithm Design and Analysis, Introduction to Databases, Introduction to Natural Language Processing, Numerical and Computational Methods, Artificial Intelligence, Optimization Methods, Deep Learning.

Data Science and Big Data Technology (Engineering Degree), for example, at Renmin University of China, is jointly taught by the School of Statistics, the School of Information, the Institute of Statistics and Big Data, and the Institute of Mathematical Sciences, to cultivate professional data science talents to cope with the opportunities and challenges brought by the era of big data.

Major courses include: mathematical analysis, advanced algebra, general physical mathematics and introduction to information science, data structure, introduction to data science, introduction to programming, programming practice, discrete mathematics, probability and statistics, algorithm analysis and design, data computational intelligence, and introduction to database systems.

Foundations of Computer Systems, Parallel Architecture and Programming, Unstructured Big Data Analytics, Introduction to Data Science Algorithms, Topics in Data Science, Data Science Practice, Practical Internet Development Techniques, Sampling Techniques, Statistical Learning, Regression Analysis, Stochastic Processes.
