   RE: [xml-dev] XML faster than mySQL database ?

[ Lists Home | Date Index | Thread Index ]

That's interesting.  Why do you think this is the case?

A:  I'm not sure so far.  Relational DBs are easy to
build, the tools are there, the skills are there, 
and I don't see XML as a compelling alternative to a 
database or XPath for SQL and XQuery looks like 
SQL.  So, right now, I don't have a compelling 
case to move away from hybrid architectures that 
use back end relational systems and front end 
markup clients.  I can see it on the client side 
clearer though.

I'd definitely rather use XSLT when it is time to 
transform, but much depends on the source.  I like XML DOM for a 
document model, that is, for manipulation of the data behind the display.

B:  Business rules in XML?  An XML Schema plus Schematron 
can do a lot, but not enough.  I still need procedural business 
objects, transaction managers, etc.

The relational db probably still will take the processing load 
a lot better than a pure XML DB system regardless of who 
is driving and possibly be a much easier development for 
the medium skilled developer.  I don't think we are nearly 
in a position experience wise to say otherwise, but I'm 
open to arguments to the contrary.  The issue is that the 
improvements have to be extraordinary, not just a small

In my mind, performance is one aspect. What is much more interesting is -

A. Is it possible to cut development cost for web applications using XML,
XML Schema, XSLT, XPath, XQuery drastically ?

B. Is it easy to make changes to this XML-based web applications to
accommodate business changes ? In other words, are this applications easier
to maintain ?

More I work with XML technologies, I am convinced that the current JSP/ASP
way of building web applications has outlived its life-cycle.
