ERP integrates the functional modules tightly. It is
not merely the import and export of data across
the functional modules. The integration ensures
that the logic of a process that cuts across the
function is captured genuinely.
This in turn implies that data once entered in any
of the functional modules (whichever of the
module owns the data) is made available to every
other module that needs this data. This leads to
significant improvements by way of improved
consistency and integrity of data.
