Questions tagged [industrial]

Industrial questions focus on topics related to applying software technologies to industrial purposes and challenges, such as the Industrial Internet of Things.

Just as the Industrial Internet of Things is a special subset of Internet of Things, industrial questions are a special subset of StackOverflow questions. Questions suitable for this tag may address, for example:

  • industrial analytics, such as for evaluating the condition of operating equipment in a military or industrial application or utility (vs. analytics for predicting buying patterns for retail or online commerce)
  • sensor networks, such as are used to instrument critical operating equipment and gather data for use in industrial analytics

For more insights into challenges of industrial data and software, see:
