size of XQuery developer community

[Daniela Florescu]

Michael,

yes, the numbers you cite are probably correct.

But I would argue that one line of XQuery needs to be implemented
with 100 lines of Java, and will generate in the long term 100 times  
more bugs,
let alone require performance improvements.

E.g. of course you needed more C developers then SQL to implement the  
same
business data management problem.

Volume alone doesn't say much.... but your point is take, we all  
understand this !

Dana


P.S. Also, Xquery is not general purpose programming language like  
Java is either
(-- I wouldn't write Photoshop or something equivalent in XQuery for  
example... :-)
