RE: [xml-dev] XML Feeds vs SQL Queries

[Len Bullard <len.bullard@uai.com>]

Hi Peter:

It's early in the project and as with most under-defined.  Initially I am
giving them a dashboard with categorized information in tab-organized
gridview/detailView combos, but an RSS Reader (rssFeed) is located in the
left panel.  Being new to implementing RSS in the web page, I'm still
weighing options.   Having the RSS client is useful for things other than
providing database information (eg, local radar and specified news feeds),
but to an inexperienced eye (mine), it seems like an ideal way to distribute
scheduled reports.   I seem to get resistance to this idea and I was
wondering if there is real world practicum for how to divide up the tasks.

To answer your question, at the moment most of the requirements deal with
information behind the firewall.  On the other hand, since it is part of a
national system, that changes post-deployment and then one loses control of
the client space (as one should).   The specs are oriented toward ebXML/SOAP
but that seems like overkill for document/messages that are one-way
(pushed).

I'd want to know more about the requirements:

- # of end users ?
- distributed or  local  (inside or outside the firewall) ?
- many or few points to be monitored ?
- is customization per individual required (feeds and / or look and feel)?

For example, if we need highly customizable distributed clients I'd
likely end up looking at XML with client side XSLT.  Or conversely, if
 no customization was required everything was local, behind the
firewall and we already had a MS environment then SQL might make
sense...
