I've not seen anything dealing with that issue (and I like to keep things as simple as possible).

Here's what I see happening. Your data entry person has a read-only copy of the database, and any changes she makes do not get recorded in the database, but a file which she then uploads to your server, and which then hopefully gets incorporated into the master database.

You can have a special program on the server to control this, where the data-entry person can chose to which of the pending updates get entered into the master.

You can build your own journaling system around that, or you can build one from the logs.

I'd like to see what you come up with ;)
