There’s a universal data model that can answer any business question. It’s called language. @ae4ai gets data to tell stories in language everyone can follow. @econ4business mises.org/library/ahmed-elsa…

I’m slowly arriving at basically the same realization many have arrived before me.
For data warehouse modeling:
Raw Data => ER/Relational model (3NF, Kimball, DV 2.0, Anchor, Activity Schema) => OBT view or materialized into a table)

Query optimization is no longer just about speed. These days it’s increasingly about cost.
Cloud warehouses will gladly run your inefficient queries and charge you for it.
A slower query that spends $0.01x is often better than a really fast query that spends $1x

Observation: many companies have dozens of data tools and only one person doing actual data analysis. What’s your ratio of Data tools to Data people? 😅
It’s quite weird that we let Facebook and other ad platforms calculate their own ad ROI. It’s like asking a student to grade their own tests; the difference between their “honest evaluation” and reality can be quite vast -- (1/2)
