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.
