xml-dev - Re: Why XML Over the Relational Model?

["Dan Holle" <dan@holle.demon.co.uk>]

IMHO, Occam's Razor between XML and DBMS revolves around data complexity and
multiple updaters.

If the XML phonebook had every US phone number, you wouldn't want to be on
the receiving end of a servlet like this.  If the query spans multiple XML
files, or does complex operations to bring together related XML elements,
you probably wouldn't want to write your own optimizer and join engine for
the servlet.  Likewise, if you have multiple people maintaining the phone
book, you probably want a DBMS approach... unless you're keen to re-invent
all the concurrency and access rights capabilities in a DBMS.

Even if you have a DBMS on the server side, XML might be the best way of
passing results and/or updates between the client and the server.
