Headless BI: How a Universal Semantic Layer Replaces Tool-Specific Models

Read Original

This article details the concept of Headless BI, an architecture pattern that decouples metric definitions from visualization tools. It addresses problems like definition duplication, tool lock-in, and AI agent exclusion by using a centralized, universal semantic layer. This allows tools like Tableau, Power BI, and Python notebooks to access consistent business logic via standard interfaces, promoting composable and portable analytics.
