Now the question is
which system owns the Customer entity? Rather, how do we address the data
stewardship issue(This is represented in the figure using the symbols "?" and " ?") ?
Data stewardship roles are common when organizations attempt to
exchange data, precisely and consistently, between computer systems,
and reuse data-related resources where the steward is responsible for
maintaining a data element in a metadata registry.
Autonomous, but Federated
Now the question is how long can these systems remain isolated? Rather, can we
bring all these systems under a central, single point of control? The fact is, systems
cannot remain isolated, and also they cannot be controlled centrally. This is because
every system needs data from every (or most) other systems. Can we then integrate
everything together into a single big system so that we don't have the problem of
integration at all? The question seems tempting, but this is analogous to attempting
to boil sea water.
Different departments or verticals within the same organization need autonomy and
so do their systems. Without the required level of autonomy, there is no freedom
which will hinder innovation.
