Dec 14, 2012 at 14:12 comment added Hernán Eche @ypercube it depends, on the first approach the table will contain id's and date ranges, etc, for same id (because there are multiple ranges for every id) so ranges will not overlap, but of course they will overlap for different id's. In the second approach they will not overlap by design because the idea is to identify (on insert) if the range was already used (slow insert) and assign a unique id for that range to reuse in the first table.
