Re: Temporal databases

Hi Philippe,
Have a look at the post I made to the pgsql-sql list I made on 6th November
2007 (day before you posted this). It contains alot of stuff for temporal
tables within Postgres.
However temporal tables (when done properly) are a very complex subject at the
best of times. It depends how much you want to integrate them. A good place
to start is Joe Celko's book "SQL For Smarties" and Richard Snodgrass'
book "Developing Time-Oriented Database Applications in SQL" - this book is
no longer in print, but is downloadable (for FREE!) from:
http://www.cs.arizona.edu/~rts/tdbbook.pdf
Richard Snodgrass is one of the leading experts in the field. I warn you - the
book is heavy going - but so worth it!!
