"read" for tomorrows class: Xquery demo and tutorial links

[Subbarao Kambhampati <rao@asu.edu>]

Folks:
 We will discuss Xquery tomorrow. Since it is a query language, it makes 
vastly more
sense if you look at the examples and play with them first rather than me 
going through
some cases drily. I suggest you look at (at least one of):

a short tutorial (parts of which I plan to use in class)
http://www.isi.edu/info-agents/courses/csci548/Slides/Xquery_Tutorial.pdf

(Here is a prose tutorial that may be easier to read:
 http://media.datadirect.com/download/docs/ddxquery/tutorial_query.html  )


http://www.cogneticsystems.com/xquery/xquery.html
 for a hands on demo (only 7 types of queries)

ps: A better xquery demo is at 
http://tamino.demozone.softwareag.com/demoXQuery/XQueryDemo/index.jsp
but it doesn't seem to be working fully.


Also the bible for Xquery is
 http://www.w3.org/TR/xquery/

 (unfortunatley it  is almost as long..)

If you are trying to compare Xquery and other query languages such as SQL, 
the following chapter may be useful:
