Model Separation
 Design layer architecture building block
 Introduced with AllFusion® ERwin® DM 4.0
 Helps modelers to focus on specific areas of
interest
 Improves overall work performance
Logical Only

Split Model
 Recommended for design layer architecture
 The new models inherit the properties from the original
logical/physical (L/P) model
 Resolves the transforms that existed in the original L/P model
 The Logical Only model becomes the model source for the Physical
Only model
 Unlike Derive Model the Split model does not create a link to the
original L/P model
Logical Only
Physical Only
