Re:  XQuery basics
Rob,

At 01:35 PM 6/4/2008, you wrote:
If you use a small main Source XML with the minimum necessary
instructions for a transform, then you can bring in the bulk the
required XML through the document function (maybe with a URIResolver
that uses XQuery, but...)

Isn't this effectively the same thing?


Don't the XML databases work best with many small documents rather than
one or a few very large documents?

I should think that depends on the database. In any case, I didn't intend to suggest that the classic architecture would become obsolete, but merely to agree that Andrew was onto something that could be very useful. For large-scale queries over aggregated data, the classic mapping of single document to single result via a single transform may not serve so well. This is where XQuery comes in. But XQuery alone is a blunt instrument for final transformations for rendering, which you are also likely to want.


Cheers,
Wendell
