Re: Recently published W3C Working Drafts (long)
Doesn't anyone else see something wrong with THREE different languages with significantly differing syntax that have roughly the same functionality (querying) with yet NONE have update or delete semantic? However some people think that the time has come for XML databases? Interesting.. PS: IMHO, until someone comes up with a language with simple SELECT-DELETE-UPDATE semantics, XML databases will be the OODBMSs of the new millenium. I remember being introduced to XML and thinking that the concepts behind relational databases were more complex than those behind the hierarchical structures that encompass XML, amazingly enough the W3C has proved me wrong by producing increasingly complex languages that supposedly deal with handling XML in databases yet have much less functionality than a simple language like SQL. *sigh* -- THINGS TO DO IF I BECOME AN EVIL OVERLORD #202 All crones with the ability to prophesy will be given free facelifts, permanents, manicures, and Donna Karan wardrobes. That should pretty well destroy their credibility. ----- Original Message ----- From: "Joe English" <jenglish@f...> To: <xml-dev@l...> Sent: Friday, December 21, 2001 6:41 PM Subject: Re: Recently published W3C Working Drafts (long) > > Michael Kay wrote: > > > To sum it up rather briefly, I think XQuery 1.0 is essentially XPath 2.0 > > plus > > 1) element and attribute constructors > > 2) function definitions > > 3) strong typing > > Of course (1) is available in a different form in XSLT 1.0, and (2) is > > available in XSLT 2.0, so you could say that apart from syntax, XQuery is > > XSLT plus strong typing minus template rules.
