Re: So after a bad year they dump a unit that generated profits for decades
Unless the data model changes, and therefore the schema and analysis change, these applications are fixed short of something like an operating system update trashing it. And if you practice enough foresight to allow the addition of fields to the model and the application self-updates to incorporate into future analyses, that's covered as well. I did one of those for an epidemiological forecasting system for a hospital. It's been some seventeen years and they are still pleased with it.
