The Data Warehouse Is Dead. Long Live the Data Warehouse.

In 1992, Bill Inmon coined the term “data warehouse” and laid out four sacred rules: subject-oriented, integrated, non-volatile, time-variant. It was a blueprint for a fortress of truth, expensive, on-premises, batch-processed, and utterly indispensable. Fast-forward three decades. The fortress has been replaced by something that resembles a hyperscale cloud platform. This platform can run your AI models and your CEO’s dashboard simultaneously. Welcome to data warehousing in 2025.

Introduction

The data warehouse has undergone a profound transformation over the past decade. Expensive, rigid, on-premises systems were once built for batch reporting. These systems have now evolved into cloud-native, highly scalable platforms. They are designed to meet the demands of today’s data-driven organisations.

Hype and Misleading Claims Surrounding Data Lakehouses

Martyn Rhisiart Jones

Segovia, 20th Devember 2025

A data lakehouse is marketed as a hybrid architecture. It combines the low-cost, flexible storage of data lakes. These lakes handle raw, unstructured data at scale. It also offers the structured querying, performance, and ACID (Atomicity, Consistency, Isolation, Durability) transactional capabilities of data warehouses. Vendors like Databricks coined the term. Snowflake and others promote it as a platform for analytics. It serves AI and machine learning needs. This approach eliminates data silos and reduces redundant copies. It enables cost-effective scaling through open standards and decoupled storage and compute models. However, much of this is hype driven by vendor marketing. Vendors promote it as an evolution from “data swamps” (unmanaged data lakes) and rigid warehouses.

The Medallion Architecture, or: How We Learned to Stop Thinking and Love the Bronze Table

Somewhere, right now, as you read this, a data engineer is renaming a table. Again. They’re calling it Bronze, because that’s what the priests say it must be called. Bronze. Not “raw”, not “stuff we barely understand”, not “this arrived at 3AM and no one knows why”. Bronze. They do it solemnly, reverently, like a monk copying out the Book of Leviticus but with YAML. And when they are done, they will feel a sense of calm, because order has been restored to the universe. Temporarily.

Para empezar por el principio

Este es el primero de una serie de temas de conversación sobre gestión. El nombre “Liderazgo 7s” se inspiró en el rugby, posiblemente el deporte emblemático de mi juventud y del país de mis padres, Gales. De hecho, gran parte de lo que aprendí sobre liderazgo durante mis años de formación provino de influencias como el rugby union.

Aquí están los primeros siete temas de conversación que abordan aspectos de liderazgo, entrenamiento y gestión.

Punto de liderazgo 1: Tenga siempre un plan B

Cando o fío aprendeu a falar

Os soldados nunca se decataron dela.

Sentouse onde sempre se sentaran as mulleres. Estaba xunto á fiestra e á estrada. Estaba preto das vetas de ferro da vía férrea. Tiña as mans ocupadas, o seu ollar suave. O amor estaba nos seus ollos. A música lenta das agullas repiqueteaba coma a choiva sobre a lousa de Bethesda. En Gales, chamaríanlle cynefin, o consolo do coñecido. En Galicia, as cousas sempre se fixeron así. Máxica, misteriosa e consciente.

Als Garn sprechen lernte

Die Soldaten beachteten sie nicht.

Sie saß dort, wo Frauen seit jeher saßen. Am Fenster, an der Straße. Nahe den Eisenadern der Eisenbahnlinie. Ihre Hände waren beschäftigt, ihr Blick sanft. Liebe lag in ihren Augen. Das leise Klicken und Klappern der Nadeln klang wie Regen auf dem Schiefer von Bethesda. In Wales hätte man es Cynefin genannt, die Geborgenheit des Vertrauten. In Galicien, wie es seit jeher üblich ist. Magisch, geheimnisvoll und achtsam.

Quand la laine a appris à parler

Les soldats ne la remarquèrent même pas.

Elle était assise là où les femmes s’étaient toujours assises. Près de la fenêtre et au bord de la route. Non loin des rails de la voie ferrée. Ses mains étaient affairées, son regard doux. L’amour brillait dans ses yeux. Le doux cliquetis des aiguilles résonnait comme la pluie sur l’ardoise de Bethesda. Au Pays de Galles, on aurait appelé cela du « cynefin », le réconfort du connu. En Galice, c’était la tradition. Magique, mystérieux et empreint de sérénité.

What is Hasbara?

Hasbara, a Hebrew term meaning “explanation,” refers to Israel’s public diplomacy and propaganda efforts. These efforts aim at shaping international opinion in favour of its policies. This is particularly true regarding the Israeli-Palestinian conflict. It transcends mere PR. It functions as a strategic tool to control narratives, delegitimise critics, and portray Israel as a perpetual victim. It justifies its actions, including occupation and military operations. Government entities like the former Ministry of Strategic Affairs coordinate hasbara. It involves state funding. Volunteer networks and partnerships disseminate pro-Israel messages globally.
