Re: Temporal database feature on IBM i?

[Peter Dow <petercdow@xxxxxxxxx>]

Hi Matt,

That feature is part of DB2 for Linux and Windows. I almost had an
opportunity to use it for a client, but they bought some packaged software
instead.

Looked pretty nice - you could set things up so users can see their data
for a particular point in time without having to do anything if you set up
the queries correctly.
