Data warehousing eschews iterative development?

Martyn Jones, Santander, 10th October 2024

Narrator: The development method for data warehousing, whether following Inmon or Kimball, has always been iterative with apparent aspects of self-service, agility, rapid development and end-user development.  

Dud: We always built data warehouses iteratively, didn’t we, Pete?

Pete: Yes, that’s right, Dud. Iterations are delivered in increments. Small enough to be quickly deliverable. Large enough to be significant to the business.

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?

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Data warehousing is out of date?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?”

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.
