xml-dev - RE: Relational Tables and structured documents

[Charles Frankston <cfranks@microsoft.com>]

This is a fine application for XML.  As several people have pointed out,
schema extensions would be rather helpful for defining how to express
relational-style joins. Sudarshan Purohit [sudar@pspl.co.in], rightfully
pointed out that XML-Data has facilities for this.  Look at
http://www.microsoft.com/standards/xml/xmldata.htm#References.

	Subject:	Relational Tables and structured documents

	I have been spending the last two weeks working on a molecular
application
	which essentially consists of relational tables.  The application is
	largely hierarchical (a protein molecule) so that it benefits from
being
	recast into structured document form. I have therefore found it
useful to
	create routines which generate nodes in a tree as a result of
joining tables.

	I expect this is a common operation (e.g. creation of orgCharts from
	relational tables).  XML would seem to provide a useful approach,
	especially client-side (most humans don't read relational tables
very
	well).  Excuse my ignorance, but is this a sufficiently generic
application
	that there are well-understood rules for it and is there scope for a
	generic XML approach?
