In recent years, companies and government agencies have come to
realize that the data they use represent a significant corporate
resource, whose cost calls for management every bit as rigorous as
the management of human resources, money, and capital equipment.
With this realization has come recognition of the importance to
integrate the data that has traditionally only been available from
disparate sources.
An important component of this integration is the management of the
"metadata" that describe, catalogue, and provide access to the
various forms of underlying business data. The "metadata
repository" is essential keeping track both of the various physical
components of these systems, but also their semantics. What do we
mean by "customer?" Where can we find information about our
customers?
After years of building enterprise models for the oil,
pharmaceutical, banking, and other industries, Dave Hay has here
not only developed a conceptual model of such a metadata
repository, he has in fact created a true enterprise data model of
the information technology industry itself.
