Nonsense. SQL has been out for decades, and I still cannot trust performance when I "do the right thing". There is a reason why DBAs with wizard tuning skills can charge a kings ransom for their services. If XQuery goes down the path of promising the sort of "app goes poof" panacea that Relational wonks have spent decades promising, you're already doomed. Developers know better. They're not buying. > Moreover, even if the performance would NOT be comparable (which I > doubt anyway but...), > the difference in productivity is SO big..... No its not, and for a sufficient wager I'm willing to put my code where my mouth is. I'm sure I can win a "productivity" bake-off using available Python/XML tools any day against any XQuery machine. I can say the same for most of my colleagues. I'm sure everyone thinks their own tools are most productive. You might as well leave such vague and useless claims out of the debate. -- Uche Ogbuji Fourthought, Inc. http://uche.ogbuji.net http://4Suite.org http://fourthought.com Use CSS to display XML - http://www.ibm.com/developerworks/edu/x-dw-x-xmlcss-i.html Full XML Indexes with Gnosis - http://www.xml.com/pub/a/2004/12/08/py-xml.html Be humble, not imperial (in design) - http://www.adtmag.com/article.asp?id=10286 UBL 1.0 - http://www-106.ibm.com/developerworks/xml/library/x-think28.html Use Universal Feed Parser to tame RSS - http://www.ibm.com/developerworks/xml/library/x-tipufp.html Default and error handling in XSLT lookup tables - http://www.ibm.com/developerworks/xml/library/x-tiplook.html A survey of XML standards - http://www-106.ibm.com/developerworks/xml/library/x-stand4/ The State of Python-XML in 2004 - http://www.xml.com/pub/a/2004/10/13/py-xml.html
