Data warehousing is out of date?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.

Make data silos to avoid data silos – Data Dialogues

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.

Data warehousing stands in the way of progress? (The Data Dialogues, Nov 2024)

Data warehousing stands in the way of progress?

“Never discourage anyone who continually makes progress, no matter how slow.”

Plato

Narrator: Let us start with a softball question. The kind that even your granny could have knocked out of the park.

How does a business describe the value it gets from accessing and analysing fresh quality data to decide what is strategically, tactically and operationally preferable for the future of the industry?

It’s not a trick question, but a tricky one that is as hard to grasp and come to terms with as a mightily greasy piglet with a very questioning tail.

What do Pete and Dud think about that? Get ready kiddies. Let’s take a peek…

The Data Dialogues (Nov 24) If in doubt, blame the data

If in doubt, blame ‘data quality’

Narrator: It doesn’t matter what you are trying to do, or even if you know what you are trying to do, but if in doubt, blame the quality of the data. There was a time when data quality was a massive impediment to business data integration.

Data quality assurance was a glint in IT’s eye. A far-away place that nobody knew how to get to.

Talking Book

Martyn Richard Jones, A Coruña, Spain.

Remember

To set the scene, get to the point, and give this thing the well-deserved impulse, impetus, and notoriety, I will begin like Dylan Thomas in Under Milk Wood—that is, at the beginning.

And for folk who struggle with big words? That’s the start.

So, to get things rolling modestly, I will explain where I am coming from with this demanding, triumphant and considered endeavour of mirth, myth and mysticism.

And, if that fails, we move on. Right? Right!

To begin at the beginning

“The data warehouse is dead. Long live the data warehouse.”

Afilonius Rex

“Ignore the hyper-nonsense about the data lakehouse, the digital doghouse, the information outhouse and the big bricking-it massive. Even if some really smartish dude tells you otherwise.”

Seneca

Heads up data, information, and knowledge people. Listen to me! If you are so of a mind.
