Data Warehousing means monolithic and siloed teams?

“Great things in business are never done by one person;

they’re done by a team of people.”

Steve Jobs

Martyn Richard Jones, Tours, 4th October 2024

Narrator: There is a widespread belief amongst the know-it-all crowd that data warehousing and business intelligence necessarily mean monolithic and siloed teams. And that the only way of moving away from such team organisations is to kill off data warehousing. But is this really a rational, coherent, and cohesive approach, as some people say it is? Or is it destructive stupidity born out of conceit, ignorance, and arrogance?

“Logistics is all of war-making, except shooting the guns, releasing the bombs, and firing the torpedoes.”

ADM Lynde D. McCormick, USN

Martyn Richard Jones, Córdoba, 3rd October 2024

Narrator: Here is a billion-dollar question: Can Agile-to-Scale be effectively used to fight a war, a regional conflict, or a global existential threat?

Were relational database management systems first used for transaction processing?

Martyn Richard Jones, Madrid, 3rd October 2023

Narrator: Relational database theory is over fifty years old. Relational database technologies go back more than four decades. Some claim that relational databases were first used for online transaction processing applications. Say what?

The data warehouse is the place to copy exhaust data to

Martyn Jones, Bilbao, 2nd October 2024

Narrator: Not all data we have is related to strictly business domains such as products, organisation structure and corporate real estate. A lot of data we collect is simply about monitoring all aspects of IT, applications, networking, security and governance. To name just a few.

Dud: What’s all this data in my exhaust? Is my data back-end going well, or do I have a mechanical data governance issue? All this OLTP exhaust data is so tedious and tiring.

Data warehousing is out of date?

Martyn Jones, Manhattan, 29th September 2024

Narrator: According to some data-mesh folk, data warehousing is “a data management construct that dates back to the eighties,” I have a problem with that. It’s as if that was somehow a bad thing. Is it? For me, that’s quite a weak argument that, in a way, treats people as if they were idiots.

It is like someone asking Newton, “So, Sir Isaac, you don’t still believe in that old gravity nonsense, do you?”

Data Warehousing means monolithic databases?

Martyn Jones, Brooklyn, 27th September 2024

Narrator: Another false meme doing the rounds is that Data Warehousing necessarily means monolithic databases. This is not what data warehouses have been for many businesses.

Domain orientation or subject orientation?

Martyn Jones, New Jersey

Narrator: Here, in this piece, we wander down Differential Avenue to look at what people consider domain and subject orientation. This story is about the good, the embarrassingly lousy hyperbole and then the ugliest provocative nonsense.

Just because you can say it doesn’t mean that you can do it

Martyn Jones, New York, 25th September 2024

Narrator: There is a fascinating famous saying, “Just because you can write something, draw something, or say something, doesn’t mean that you can do it”, that I think could be further explored in the context of data and analytics. It seems to go hand in hand with expressions such as “It must be true because I read it on the internet”. Also, it can be pretty surprising how many businesses expect their people to lie where it’s practical and commercially beneficial.

The best way to avoid creating data silos is to develop a plethora of data silos?

Narrator: Data Warehousing is an excellent integrator; it is the cohesive melting pot of data and the best-known way of providing multiple valid versions of the truth depending on who is looking at the data, when they are doing so, and from what perspective.

Physician, heal thyself!

Narrator: Consider this. If the originators, acolytes and sycophants of data mesh hadn’t been so free and easy with how they created and perpetrated technical debt, especially data model and data quality-related technical debt, then we wouldn’t need data mesh to try and get us out of the mess these sloppy developer people put us into in the first place.
