Quality information fundamentals which are based on the IoT edge technology has been established as an information infrastructure to manage digital data that were managed individually in various locations throughout the plant and business, and to make new discoveries using digital technologies such as mathematical science and artificial intelligence. Requiring edge computing programming environments, many have not evolved beyond early communication models using traditional message queues. On the other hand, the software development environment for IoT, especially in the U.S. and Germany, has evolved dramatically, and a flexible and efficient programming environment is being established. In this session, we will discuss practical approaches to IoT, from the basics of quality information fundamentals to the latest programming models.
