Mention ‘Big Data’ and most people think immediately about retailers storing customer information, the rapid rise of social media and vast numbers of financial transactions taking place online. However, engineers and scientists in test and measurement environments are contending with even bigger volumes of big data. This is data of a different kind. It is the biggest, fastest and oldest big data and it demands its own classification.
National Instruments coined the term ‘Big Analog Data’ to describe the hugely valuable data that is drawn from a wide range of physical parameters including vibration, temperature, acceleration, pressure, sound, image, RF signals, magnetism, light and voltage.
One of the best examples of Big Analog Data in Europe can be found at the CERN Large Hadron Collider. When an experiment is running, the instrumentation can generate 40 terabytes of data every second.
