Big Data

The online shop we trust is currently offering the very product we’ve had our eyes on for a long time at a cut price. That may seem like chance, but is actually the result of higher mathematics and refined analytics. Our actions in the digital world generate incredible amounts of data day after day. That data makes our life easier, but also leaves tracks on the web. Do we like it best when the light in the living room is a warm orange? Do you prefer to have lounge music coming out of the smart loudspeakers at breakfast on a Sunday? Or the heating in the bathroom to be automatically adjusted to a pleasant 24 degrees in the evening? That can be done simply in the home, but we also encounter something similar in a far more complex form in modern connected factories.

People, things and machines produce incredible amounts of data: currently 16.3 zettabytes per year, a number that will grow tenfold by 2015. “Big data” is an extremely valuable resource. It’s changing the way we communicate: We reveal more and more information about ourselves, which is then stored and processed on servers and in clouds. What are the advantages and disadvantages of that? And what about the data’s security? These “Discoveries” deliver the answers.
