    The point I was trying to make is that these are no longer
    exceptions, they are the normal mode of IT programming nowadays.
    For example we recently bought a bulk billing system - the
    epitomy of batch processing applications. Except this new one
    does everything except print the bills in real time, there is no
    batch option! Now just how far it can scale using that approach
    remains to be seen, but we are certainly processing several 10s
    of thousands of bills per month and ultimately aiming for
    millions (and fairly soon!).

    Absolutely. I agree with the categorisation that IT stuff is data
    drivem, its just an observation that data driven used to be
    synonymous with batch processing but nowadays it is much more
    often using distributed applications in near real time.

    This is definitely true. We have one large team who do nothing
    but build MIS systems and data warehouses. The demand for MIS is
    such that they are never short of work either!
