The book provides an overview of the current use of Big Data in various fields, as well as the associated opportunities and risks. It introduces new degree programs that enable handling Big Data and addresses data protection requirements and standards relevant to the use of Big Data. Big Data, which refers to large, complex, and rapidly changing data sets, is increasingly analyzed in academic social research, market research, and official statistics to answer relevant questions.
