FYI, if the logs in question belong to a "financial system" (a true accounting application), then changing those logs is against the law - as far as Sarbanes-Oxley is concerned.

Seems like the reversal would be a logged event as well.

I've always thought direct edits to any log by a user or even an admin corrupts 
the integrity of the log and invites unlogged edits to be made. Asking for 
trouble depending on the critical nature of the data changed.

If your clients are anything like my clients, make sure you allow them access 
to change the historical dates after they've changed the price. Someone is 
bound to change the price at the wrong time and need to go back in and adjust 
it.

One of my clients asked about a history of price changes.  Easy enough
to implement programmatically for the few price fields, but then I got
to wondering if simply putting code in the ON UPDATE trigger to send
the
old record to a "history" table would be a more complete (and long term

EASIER) solution, whereby my app would query the "history" table for
changes.

Your thoughts for tracking price (or other) changes?
