In an era characterized by overwhelming data proliferation from websites, devices, and services, the ability to organize and analyze this information is crucial for informed decision-making and understanding customer behavior. This tutorial demonstrates the construction of real-time analytics using Keen IO and PubNub, platforms that facilitate the collection, exploration, and visualization of data without the need for managing a personal database. Keen IO offers analytics as a service, enabling users to track events from various sources and perform customized queries without SQL, while also providing complex visualizations and reporting capabilities. The process involves server-side code to publish event data to a PubNub channel and transfer data to Keen IO using scheduled tasks via Cron jobs. This setup is ideal for scenarios requiring the real-time transmission and analysis of diverse data streams, such as assessing microclimates, with Keen IO's inbuilt functions aiding in deriving insights from the aggregated data.
