In current applications, delete is not reversible, therefore delete is not given to normal users, which causes major frustrations.

To improve the user experience, the following should be developed:

• when an object is deleted, it stays in the database with a flag
• deleted objects are not visible in normal applications
• there is a possibility to restore deleted data, following the same business rules as the ones for delete (if sub-objects are deleted when main object is deleted, then restoration of main object should also bring back the sub-objects)
• in any conflict on number when restoring, then the number of the restored object will take a suffix to make it unique.
