This document discusses analytics at the edge in Internet of Things environments. It provides an overview of edge computing and examples of edge devices. It then introduces Apache Edgent (formerly Quarks), an open source programming model and runtime for streaming analytics at the edge. The document also discusses using the Informix database for analytics on sensor data both at the edge and in the cloud, and it demonstrates connecting Edgent to Informix on a Raspberry Pi for real-time sensor data analysis.
