Build OLAP Cubes With AI (Star Schemas in Practice) | From Excel to Product (Ep. 4)
Jul 1, 2026
Can an LLM build your OLAP layer? I have Claude write a Mondrian schema over a 250k-row Postgres database — and explain dimensional modelling as we go.

Episode 4 of "From Excel to Product." We turn the star schema into a working OLAP cube, with AI doing the heavy lifting:
- What an OLAP cube is and why it's worth building
- Having Claude generate a Mondrian schema from our model
- Loading 250k pharma facts and querying the cube
- Where AI helps with dimensional modelling — and where it doesn't
Chapters:
