  Big Data in IoT is a large and fast-developing area where many different
methods and techniques can play a role. Due to rapid progress in Machine
Learning and new hardware developments, a dynamic turnaround of methods and
technologies can be observed. This overview therefore tries to be broad and
highlevel without claiming to be comprehensive. Its approach towards Big Data
and IoT is predicated on a distinction between the digital economy and the
characteristics of what Robin Milner has described as the Ubiquitous Computing
System.
