- V7 includes a Snapshot facility that does this. It keeps track of
- changes to tables (inserts, updates, deletes) and stores this
- in a log for each snapshot. You could use this information in whatever
- fashion you like. Snapshots are supposed to be for asynchronous database
- replication, but I don't see why you couldn't use them for what you want.
-
- In any case, you can use post-insert, update, and delete triggers to
- log changes including pre and post values quite easily , if snapshots don't
- automatically give you everything you need.

- Hope this helps,
