Your reply need to include many specifics.
Suppose you want to track changes to the takes relation. Has this implementation's audit trail documented unauthorised database administrators or those who break an administrator's password? Specifics are needed in your response.
Imagine you want a record of every time the takes relation was changed. Is there any assurance that an audit trail of modifications made by this implementation will include actions taken by malicious database administrators (or anybody who acquires access to the administrator's password)?
