Importance of a Common Data Layer for BI and AI
summary
Gardner’s 2023 survey of 6998 CIOs surveyed shows the top AI barrier is accessing the right data, followed by volume and complexity, so the concrete claim is that a well‑designed common data model (CDM) fixes that by providing owned, high‑quality fact tables, shared dimensions, calculated attributes and hierarchies. The CDM functions as CDM as feature store, centralizing feature management, speeding model reuse, enforcing governance and using a star schema optimized for BI for faster, consistent reports.
