I worked on a mainframe for a major airline over 20 years ago. I always found it amusing that Sabre detailed my programs/jobs to cost the airline almost 7 figures a year; I never knew if that was real dollars or price to be negotiated down. Most of my programs was to repackage yesterday's flights and passenger data into CSV files so an external program can pick them up and ETL into a data warehouse. At the time, there was no utility like ODBC. I had to use JCL and SAS and my own created utilities. I even had to write a utility to output to CSV (there was none offered out of the box by IBM or SAS).
