Description:
|
This task defines the final
data model based on the logical model and evolved through the event trace
task. This model will include any technology specific design based on data
and process placement and reflect performance related design characteristics.

Physical Data Model – This is the model depicting
the actual way in which the database schema will be implemented. This model
differs from the logical data model in that it will reflect concepts like
denormalization for performance.
Replication Strategy – Assuming data will
be replicated for fault tolerance or performance reasons, this defines
the way data will be replicated throughout the architecture to
