I have a database, which has sensitive data. I want to find a way to keep it save from any changes applied by the DBA. my question will in two ways:
1- Is there any way to trace the changes and modification applied directly from the Database (changes on table level) ?
2- Could we encrypt the data to be unreadable by the tables ? and how can I keep the encryption formula away from people who access the database directly (not through an application)?
