Hi Alwin Leibbrandt,
You can change your database schema as frequently as needed. All you need to do is to merge the changes to have your class model and schema in sync. You should use the Schema Merge wizard
in order to achieve this goal:
1. Run the Reverse Mapping wizard
2. Click on the Merge button. This will open up the Schema Merge Summary Dialog. The Schema Merge Summary dialog summarizes the result of the merge operation.
3. Click on Merge. This will merge the schema changes with the existing mapping changes made.
4. Click on the Generate & Save Config button to regenerate the persistent classes.
I think that will help you. If any other questions arise please contact us.
