Batch Control Definition/Meaning:
Correctness checks built into data-processing systems and applied
to batches of input data, particularly in the data-preparation stage. There are
two main forms of batch control: sequence control involves numbering the records
a batch consecutively so that the presence of each record can be confirmed
during the data-vet run; control totals involve establishing record counts, or
totals of the values in selected fields within each record, and checking these
totals during the data-vet run. Control totals may be "meaningful", in the sense
that they may have a use (for instance to an auditor) that is additional to
their function within the system. Most commonly they are meaningless totals
(e.g. of employee numbers), often referred to as hash totals.
The scope of
batch control may extend beyond the data-vet program, for as far into the system
as batches retain their separate identities. In particular, they may be used to
check that incorrect records, rejected during the data vet, are resubmitted
before a batch is released for further processing.
