Extraction
Figure 1. Advanced Properties dialog, Extraction tab
- Case sensitivity
- Specify how case in database object names should be handled.Case sensitive: case won't be changed on database objects, Lower case: database object names will be converted to lower case, Upper case : database object names will be converted to upper case.
- Import system tables
- Check this box to include system tables in the schema.
- Ignore errors

Generation
Figure 2. Advanced Properties dialog, Generation tab
- Database schema
- Name of selected meta-schema file.
- Target database
- Specify the database to use in the script.
- Generate primary keys, secondary keys, indexes
- Specify whether to include primary keys, secondary keys, and indexes in the script.
- Use national char types
- By default, the database creation / update scripts will generate column using standard char types. If this option is set, the scripts will produce columns using national char types. For example, with an Oracle database, the column types will be CHAR or VARCHAR2 when the option is not selected, and NCHAR, NVARCHAR2 when the option is selected.
- Populate database with sample data
- Add statements in the script to add sample data to the database.
