I worked on a large pharma sales data warehouse project and we had the need to profile some complex 3rd party data feeds that were poorly documented.
I was able to write, test, and run the code (across 500Gb data) to provide the required profiling information in less time than it took to install an evaluation version of a commercial product ... which after several weeks of extensive testing (and hundreds of man hours) never produced the correct results. It amazes me what can done with simple Python scripts and a KISS attitude. Malcolm
