The problem is that MDM is a marketing moniker, just like "Big Data",
SOA, and the like. All of these monikers are deliberately generic and
borderline meaningless (by design). An ontology (in my eyes) is the
antithesis of fluffy marketing buzzwords since they force you to look at
the actual characteristics of an entity and define said characteristics
MDM is fundamentally about holistic views of heterogeneous data sources.
Basically, heterogeneous data source virtualization. (04)
Most MDM narratives pay lip service to "semantics" and rarely address
the practical realities of implementing enterprise-wide heterogeneous
data virtualization, which cannot really manifest without an ontology of
terms that defines the nature of entities and relations, in a given
Anyway, ontologies are a powerful tool for addressing the fundamental
challenges associated with practical virtualization of heterogeneous
data sources, be it at the private enterprise level or even across the
many data-silos that now constitute the world wide web (e.g., Facebook,
Google+, Twitter, LinkedIn etc..). (06)
BTW -- I've recently published a number of blog posts about data
de-silo-fication and heterogeneous data virtualization. (07)
-- Deceptively Simple Conceptual Data Virtualization
-- From Open Database Connectivity to Open Data Connectivity
-- Oracle Data De-Silo-Fication . (09)
