In fact, order is so important relational proponents insist it must be explicit and based on an ordering of some attribute or attributes. After all, the available ordering attribute sets is the powerset of the ordered attributes, times the number of available orders for each attributes, times 2 to the power of the number of ordered attributes for ascending and descending.

Ordering by location is no more meaningful than ordering by value--it's just a lot less useful and a lot more fragile. Received on Sun Jul 02 2006 - 20:13:57 CDT
