I'd also agree with my original statement. Terminology isn't always consistently applied. I don't know if he's correct or not, but the eminently respectable C. J. Date writes on p. 92 of the sixth edition of his well respected text "Introduction to Database Systems": "2. Tuples are unordered (top to bottom) This property follows from the fact that the body of the relation is a mathematical set; sets in mathematics are not ordered." This is a rather significant point in his discussion. -- +-----------------------+------------------------+-------------------+ | Elliotte Rusty Harold | elharo@xxxxxxxxxxxxxxx | Writer/Programmer | +-----------------------+------------------------+-------------------+ | The XML Bible (IDG Books, 1999) | | http://metalab.unc.edu/xml/books/bible/ | | http://www.amazon.com/exec/obidos/ISBN=0764532367/cafeaulaitA/ | +----------------------------------+---------------------------------+ | Read Cafe au Lait for Java News: http://metalab.unc.edu/javafaq/ | | Read Cafe con Leche for XML News: http://metalab.unc.edu/xml/ | +----------------------------------+---------------------------------+ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
