Hi all.
How can we manage the history of changed rows in the database. I have some
idea but not yet implemented. By using triggers to make a copy of the row
being changed to the another table in the same db. Is there any way to only
save the changed fields data and field name? Any other idea?
Thanks
CPK

I have used this convention and it works well.

I have a real problem with how it suggests using NULL. NULL is undefined,
and they are basically abusing it to mean infinite positive. NULL has issues
being indexed, big datetime values don't.

At the recent postgres convention I eavesdropped on a discussion about a
possible new temporal range format which would basically consist of a start
date and an end date and preclude any other entries from overlapping. Such
a format would be ideal for PITA, but the start and end would need to be not
null...
