Big Data


This course gives an overview of Big Data technologies. It revisits the classic ways of answering "tough questions" using data warehouses and parallel database systems. Then, it presents the modern technologies of cloud computing and massively parallel data analysis that have led to the Big Data hype. Furthermore, this course studies a number of other technologies that have been associated with Big Data (e.g., push-based, real-time data processing and unstructured data models).  The course will include a guest lecture that presents Big Data use cases from personalized medicine.
