how to monitor changes on tables automatically

[Dark Smile]

At first thank you for the answer.
The solution may work well no question but in my case i have to monitor property changes (label, mandatory, EDT) also.

Do you have any other idea or approach how to do that ?

Some more details:

i want to monitor whenever there are changes for a protokoll. Normally we comment our changes e.g. on classes or form methods. But on tablefields (and EDT's etc) it's difficult to insert a comment.
So for that i want to intervene in the insert/update/delete process so i get automatically a protokoll of the changes without doing anything manually expect the changes themselfs
