Dan Linstedt, creator of the Data Vault and CEO of the Data Vault Alliance, joins us to talk about why so many data warehouse projects fail—and what can be done differently.

From his days at Lockheed Martin, where he and a tiny team integrated 125 source systems in six months, to the core ideas behind Data Vault like raw data storage, version control, and divide-and-conquer thinking, Dan shares hard-earned lessons and clears up common misconceptions. If your company keeps rebuilding the same warehouse every few years, this episode might hit home.

🎧 In this episode of Insane Data, Giuliano sits down with a true legend in the field of process mining – Prof. Wil van der Aalst, the founder of the discipline.

Together, they unpack how data and event logs from IT systems can be used to understand and improve business processes. Wil explains the difference between classical and object-centric process mining and shares why workflow systems failed in the 90s – and how that failure sparked a whole new field.

You’ll hear why poor data quality and lack of executive support are the biggest barriers to adoption, and how organizations like Lufthansa use process mining to minimize turnaround delays at airports. Wil also reflects on how governments could benefit massively from process mining – if only they were willing to confront inefficiencies.

Finally, for those ready to start, Wil shares practical advice: open-source tools, simple data requirements, and free online courses. A must-listen for anyone who wants to truly understand what’s happening inside their organization.

In this episode, Giuliano Giannetti sits down with Bill Inmon — the father of the data warehouse — to talk about how modern data thinking actually began, and why its original ideas still matter today.

Bill reflects on a time when data was used only for transaction processing, why his ideas were once considered heresy, and how business — not IT — pushed the data warehouse into existence. Along the way, he shares his own path: from mathematician and outspoken critic of IT culture to reluctant entrepreneur, learning the hard way what it takes to stand by your ideas.

In this episode of Insane Data, Giuliano Giannetti talks with Andrew Foad, creator of the Hook methodology.

Frustrated with the pitfalls of Data Vault, Andrew designed Hook as a lightweight, flexible way to extend the shelf life of data warehouses by separating ingestion from modeling and simplifying business keys. He explains how it works in practice, why “less modeling is often better,” and where Hook could fit alongside other modern approaches like the Unified Star Schema.

👉 Tune in to discover whether Hook could change the way you think about data modeling.
