This is a very strange view of the world. Merely using a database
instead of flat files does not change the security *at all*.

With enough permissions I could edit your Oracle or DB2 database file,
on disk. I don't need to go through the Oracle library - instead, I
can just edit the files that Oracly writes (if I have the permission).

Again, this assumes I have access to the files on the disk. With
access to the files, I can trick any other industry-strength into
believing the header file was never there.

I think you are grossly mistaken in your conclusion. You can "hide"
with any other CM system just as well if you can overcome OS
limitations. Heck, I could replace the CM software *itself*.
