Use the Properties view to set the transformation properties
of attribute objects before you transform a logical data model into
a physical data model.
Before you begin
Before you modify the properties of logical data model objects,
you must open a logical data model in the logical data model editor.
Procedure
To set attribute transformation properties for logical
to physical data model transformation:
- Select an attribute object in the Data Project Explorer
or in a diagram.
- Click to
open the Properties view, if the view is not already open.
- On the General page in the Properties
view, modify the Persistent property as needed.
If you select Persistent, the attribute
is transformed to a column. If you do not select Persistent,
the attribute is not transformed. The icon for the attribute in the
Data Project Explorer or in data diagrams is changed to visually indicate
when it is not persistent.
Restriction: If
the attribute is part of a primary key, an alternate key, or an inversion
entry that is set to be transformed to an index, you cannot modify
the persistence property. These attributes are always transformed.
- Save the logical data model.
