The last Oracle data warehouse I built, for a telecom company, is the one I look back on.
I was the sole developer/designer/documenter, and handled everything from requirements through ETL (in PL/SQL) to storage and Business Objects reports.
In the last year I was developing and supporting it, it ran without error 365/24, and had complete documentation in the form of nested data flow diagrams.
Having said that, I don't miss that world. Too corporate, too commutey.
