After logical objects and relationships are defined in a logical
data model, the model can be transformed into a database-specific representation
in the form of a physical data model.
You can use a wizard to transform logical to physical data models. Before
you transform a logical data model, you must set transformation preferences
and logical object transformation properties. Then you can use the wizard
to specify additional transformation options.
You can transform a logical data model into a new physical data model,
or you can transform a logical data model into an existing physical data model.
This function is useful in the following scenarios:
- A logical model is transformed to one or more physical models, then changes
are made to the logical model. The changes can then be propagated to the existing
physical models.
- Parts of a larger logical model are being worked on by different team
members. Each team member can transform their part of the logical model to
the same physical model.
