The most common type
of deployment for SAS MDM is the physical
deployment model. This model assumes that all the information necessary
to construct a complete survivor record for an entity is stored in
the hub. Source system keys are also stored in the hub so that information
used to identify and describe entities can be recorded. This supports
the ability to link or reference source system data, provides traceability
for the contributor records, and describes key relationships with
the data as it exists in the hub.
With this approach,
uniquely identifying information for entities is stored in the hub,
along with other dependent attributes. You can access the survivor
record by querying the hub by itself, without the need to refer to
the systems of record. This approach simplifies the task of constructing
the survivor record, but results in higher storage requirements.
The physical deployment
model is the primary implementation, but SAS MDM
also works in conjunction with other technologies to provide functionality
that supports deployment styles such as hybrid MDM, registry-based
MDM, reference-style MDM, and other integration scenarios.
