This, admittedly contrived, example demonstrates quite clearly the
fundamental difference between event driven (read, "on-line") and
non-event-driven (read, "batch") processing. OO lends itself to event driven
processing; procedural programming doesn't. That is why OO is taking over
the world... (whether the people using it understand this or not... all they
know is that Objects are flexible and responsive and designed to handle
events; procedural code simply isn't...)
While I can believe that COBOl will eventually be retired, I don't
believe batch processing will ever completely go away. Events such as
are invoked by as tax authorities wanting yearly company accounts and
tax computations are probably too much to suddenly throw at an on-line
system, there would probably be severe degradation of service, even if
many of the underlying figures had already been calculated. Events
such as monthly/weekly payrolls, cheque printing, etc also are probably
best done in a batch process.
This is a good question. How would these processes be handled in an "on-line" way? I know you wouldn't have to actually have to calculate payroll until it was time to generate the direct deposit/print the che[ck|que], but doing this serially for all active employees on a certain date would seem to be, at best, "online with a driver."
Pete, What would be your online vision of how this would take place? (You know, once you're done with the beach party and all...) ;)
