Business Intelligence in the Age of AI: Modern Data Warehousing, Analytics and AI-driven Decision-Making

By Dr. Florian Detzel

AI answers any question about your data. Whether the answer is right is still a BI problem.

Every analytics team now has natural language queries, copilots, and dashboards on demand. Ask an ungoverned model the wrong question and it responds anyway: fluent, confident, and wrong. The gap between fast and correct is exactly what this book closes.

Business Intelligence in the Age of AI is a guide to the judgment behind that gap, covering everything from the data warehouse to the AI copilot sitting on top of it, and what has to be true along the way for either one to be trustworthy.

This is not an AI hype book. It is a map of the modern analytics stack, built around one continuous case study: a fictional rental company called Avelto Rentals. You see how a single business question travels from raw operational data all the way to an AI generated answer, and where it can quietly break along the way.

What you'll be able to do

Build data warehouses, star schemas, and dimensional models that keep numbers consistentDesign dashboards, KPIs, and scorecards that drive real decisionsUse metadata, lineage, and data quality to keep semantic layers honest, and any AI sitting on top of themKnow which problems lakehouses, data mesh, and real-time pipelines actually solveWork with LLMs for SQL, DAX, and Python, build RAG pipelines, and judge a copilot's answer instead of just accepting itUnderstand agentic analytics, self-service BI, and the skills that will matter as AI takes over the front end

Who this book is for

Analysts, BI developers, data engineers, data stewards, students, and decision-makers who want more than a list of tool names. People who need to understand why a BI system is built the way it is, so they can tell a trustworthy answer from one that merely sounds like it.

Why listen to the author

Dr. Florian Detzel has spent his career on both sides of Business Intelligence, first as a university educator who had to make complex data concepts click, then as a practitioner building data warehouses, models, and analytics platforms with tools like Power BI and MicroStrategy inside real organizations. As founder of BI Academy, he teaches AI as a powerful new front end for BI craft, not a replacement for it.

The tools will keep changing. The judgment this book teaches won't.
