Re: Table Timemachine!

There is a presentation about journaling databases available at:

http://conferences.oreillynet.com/cs/os2002/view/e_sess/2551

The basic idea is that with database journaling you can extract
a snapshot of the data at any past date. At the time of the talk,
the speaker said he was going to make the code public. I don't know
if this was ever done.
