The relation of attributes within each entity and between unsorted entities in the table/relation.
That is still simply a flat table. Define it however you wish. It's intended to be a simple and flat table, by design. Now there would be structure if these row/entities were sorted. This is yet another complaint, as I understand it, not merely of things like autonumbering, but of something like XPath, which does collect sets, yes, but collects them in order, top to bottom, even to including a position() function. It becomes an ordered set, even an ordered relation. Received on Tue Feb 21 2006 - 23:52:19 CET
