When you think of data science and its applications, you may think of a world where artificial intelligence and data meet to solve real-world problems. This view is somewhat accurate, but it only represents a small fraction of data science’s many purposes and use cases. Data science is an interdisciplinary field that combines computer science, statistics and mathematics to analyze data sets and find insights across a variety of software platforms and databases, businesses, industries and levels of complexity.
