Generating logical data models from physical data models
You can use a wizard to transform physical to logical
data models. Before you transform a logical data model, you must set transformation
preferences. Then you can use the wizard to specify additional transformation
options.
Setting data type mappings for data model transformation
You can set data type mappings for data model transformation by using the Preferences window. These preferences are used to define how logical data types are mapped to physical data types during logical to physical or physical to logical data model transformation.
