>> ODS has a schema applied to it to make the data fit into a relational database structure.
Yes, I get that. I was probably oversimplifying.
Practically speaking, the BI projects I've been on for small to medium enterprises (<150M in size, non-tech) still have predominantly relational data sources.
In many of those cases, a warehouse is an expensive effort in over-engineering, but a data-lake-like ODS (without transformations in the main data tables) with curated subject-area marts is a more sensible solution.
To me, it looks more like an ODS (Operational Data Store) with some data-mart like curation steps before it hits users.
