TUTORIALS > LOGICAL AND PHYSICAL MODELING
Finished! After the split the Custmr table will be two physical tables that look like this:
The two tables are identical except for the name.
You can selectively choose which attributes are included in the resultant tables by using a vertical split.
The denormalization mapping is stored in the data model tree underneath the submodels. You can use this to undo
the operation or see the history of what happened. ER/Studio tracks the before and after states of these operations.
This comes in handy in the next section where we discuss the Where Used analysis that can be performed between
the logical and physical models.
Finding out How an Entity Maps to the Physical Model
Now that we have performed a denormalization operation, the logical entity, Customer, essentially has become two
physical tables, Custmr_East and Custmr_West. The ties between the logical and physical models are not lost.
ER/Studio allows you to see what Customer in the logical model maps to in the DB2 physical model.
Let’s take a look at the Customer entity in the logical model.
1 In the Data Model Explorer, navigate back to the Customer entity in the Logical model
2 To start the Entity Editor, double-click the Customer entity.
