A few years ago I did some work for a stock&commodity data retailer.
They had historical data plus real time satellite feeds and they sold
requested data to dial-up customers (in the style HP nowadays calls
an E-Service)..
One project involved their buying historical stock price data from
another vendor and merging it with their own - filling gaps and
correcting errors. This involved a substantial volume of data and
algorithms and heuristics to distinguish error from price
fluctuations, splits, etc. I used an Ada 9X beta compiler. The
database prices were already stored as fixed point with a delta of
1/8. The main program copied and merged, spinning off questionable
situations to a task that displayed a price history graphically for a
human decision maker.
I well remember one early demo where the program got a
Constraint_Error at such and such a line number. Within a few minutes
I had it explained, fixed, recompiled, and was re-running the demo.
The client was impressed. In C there would have been no error, just
bad data in the database.
As of last year the company was still growing (they asked me for
changes to handle some new hardware).
