hmm, it seems to map to my workflow with Clojure lately. But there I'm massaging and generating new data sets (even though it's statless) but I can see that if you have a very settled data format then this would work in a language agnostic data-interface kind of way. I could see like measurement/time series data being stored in SQL and accessed that way would be much cleaner than opening and closing CSV files for all sorts of datasets
