accelerates. This phenomenon is pretty much true for every organization.
Another way to look at this accumulation curve is shown in Fig. 1.6.8.
Fig. 1.6.8 Different and dynamic bands of usefulness of data over time.Fig. 1.6.8 shows that as data accumulate over time in the corporation, there are different
and dynamic bands of usage of data. There is one band of data that shows that some data
are heavily used over time. There is another band of data for lightly used data. And there
is yet another band of data for data that are not used at all.
As time passes, these bands of data expand.
Usually, the bands of data relate to the age of the data. The younger the data are, the
more relevant the data are to the current business of the corporation. And the younger
the data are, the more the data are accessed and analyzed.
