Doctors and nurses gather high volumes of data on a daily basis. Over 2.5 exabytes of data were measured on a daily basis in 2012, from the healthcare industry. From patient histories, laboratory test results, diagnosis, to drug prescriptions, hospitals are a goldmine of medical information. Electronic health records (EHR) alone gather data at lightning speeds. The healthcare industry’s collective data can be described as high volume, high velocity, and high variety—in other words, there is the potential to gather and analyze big data. Volume is the amount of data measured in petabytes or terabytes; variety is the different types of data such as video, text, audio, and log files; velocity is the speed of data processing streams from sources such as mobile devices and machine-to-machine transfers.
