Building an AI-First Data Architecture (starting with Tableau)
The biggest hurdle for AI in the enterprise isn't the algorithms—it’s the meaning.
If you ask an AI, "What happened to sales?" it can look at the data. But if you ask, "Why are our 3-month rolling averages dipping?" the AI needs more than just a table; it needs to understand the Semantics of that calculation.
I’m using a four-tier metadata framework to bridge the gap between "Raw Code" and "AI Intelligence." This isn't just about documenting for humans; it’s about creating a machine-readable map of Business Intent.
