Is Order part of a result set? This question got me thinking:
ROW_NUMBER() OVER (PARTITION BY B,A ORDER BY C) doesn&#39;t use index on (A,B,C)
In it the questioner states two functions give the same result set, however they don't in that they have identical rows but they are always in different (and consistent) orders.

Is the order of a result set part of the result set? Wikipedia implies no (but doesn't strongly determine an answer, nor does it speak from a position of authority):

Is 

Sector  Name
A   Alpha
B   Beta


the same result set as

Sector  Name
B   Beta
A   Alpha


I personally only work with SQL Server, does the answer change by platform? Is the answer a matter of opinion only? (If so please give answers of fact only, or of consensus by professional bodies at any rate- not your personal opinion please)
Possibly the ANSI 92 definition held at

http://www.contrib.andrew.cmu.edu/~shadow/sql/sql1992.txt

gives the answer. Section 3.1 Definitions seems to draw a distinction between the idea of a result set and a result sequence. The distinction was not in my awareness when I wrote the question using the former phrase


  v) sequence: An ordered collection of objects that are not necessarily
  distinct.
  
  w) set: An unordered collection of distinct objects. The collection
  may be empty.
