Is the end_date always knowable at record insert?

Rob,

  Not always. Sometimes projects have known end dates, other times the end
is interminate until it happens.

CHECK(end_date is null or start_date <= end_date)

  So a default of NULL should be applied, or just allowed to happen?

Thanks,

Rich
