Learn big data with online courses
What is big data?
Big data refers to the analysis of large data sets to find trends, correlations or other insights not visible with smaller data sets or traditional processing methods.1 The exponential growth of internet-connected devices and sensors is a major contributor to the large troves of data that exist today. The storage, processing and analysis of data can require hundreds or thousands of computers. Breaking down the big data definition, an example can be found in the development of the autonomous vehicle. The sensors on self-driving vehicles are capturing millions of data points that can be analyzed to help improve performance and avoid accidents.
