Model Preferences

You can set the following model preferences:

Allow NOT NULL for non-identifying mandatory relationships-This feature allows the user to choose how non-identifying mandatory relationships are implemented during transformation and re-transformation. They were implemented as NULL but with this feature they can be implemented as NOT NULL.
Generate comments in DDL-This feature applies only on the IBM DB2 database. When generating DDL, any comments that are associated with the generated artifacts are included in the generated DDL. This feature lets you specify that these comments must not be included in the generated DDL.
Use VARCHAR instead of LONGVAR for DB2 text fields > 4000 characters- This feature applies only on the IBM DB2 z/OS. The implementation type for DB2 text attributes whose length was greater than 4000 characters was LONGVAR. This datatype is being deprecated by IBM so this feature lets you select VARCHAR instead.
Limit the number of characters in the Inline Code statement.
