Look up the ressearch done by Rick Snodgrass at the University of Arizona, and get a copy of his book on temporal databases from Morgan-Kaufmann. He is the expert in this area.

The fundamental problems deal with the fact tht time is a continuum and SQL is based on discrete elements. You need a very previse model of time to compare and deal with durations. Received on Mon Jul 29 2002 - 18:16:21 CEST
