I'm in the process of adding more historic information to one of my
databases. I've liked the theoretical treatment of the concept in
"Temporal Data and the Relational Model", by Date, Darwen, & Lorentzos.
A lot of it is not realizable without a lot of user defined
types/functions/etc. I was wondering if anyone else has tried to use
their approach as a base for their historical databases in PostGreSQL
and has any "lessons learned" to share.
Thank you.
