Why wouldn't one use security provisions to deny access to the file
excepting from the module/program/whatever that is defined as the file
handler(s)? So far as the ability to write reports is concerned, one could
decide to allow read access, or one could write an access progam that
provides the fields & rows as appropriate? 
 
So far as the concern that management will just bypass it all by replicating
the data, etc... well... it is their data afterall. If thats their decision
then probably the files should have been left open in the first place. If
your data integrity decisions are not reflecting management's desires then
you have really dropped your drawers, anyway, haven't you?

Joe,
 
I think you're method would be effective. Can the before read trigger be
done to actually enforce this? If someone tries to read the file outside
of the I/O module will the read be denied? For example, *BEFORE cannot be
associated with *READ. Thus wouldn't the application already have the
data on an *AFTER *READ? And the best you could hope for is notifying the
police that someone stole your horse instead of stopping the theft in the
first place?
 
I bet this method, however, would make it extremely difficult for anyone
to use any existing reporting tools, etc. The problem I have with that
is, once again, the iSeries will be seen as the culprit and not the
methodology. And again the corporate answer will be to either replicate
all the data, or move the application entirely off of the iSeries, to
facilitate the reporting tools.
