Lightweight Business Intelligence with Ruby, Rails, and MongoDB
summary
Claims a working lightweight BI built with Ruby on Rails, an event-sourced Leviathan, and MongoDB on the backend that captures every message from RabbitMQ, stores denormalized facts, and keeps statistical aggregates updated as events arrive. ETL overnight jobs become streaming updates, report latency drops to seconds, queries avoid heavy joins, APIs expose real-time metrics, and the implementation runs in production rather than just a design exercise.
