To Quiz or not to Quiz...

Thanks Bob
Web services are, from my understanding, executable objects that exist
somewhere on a network that can be called via XML commands to perform some
special action. They usually, but not always, do not return any information
to the calling program. Advantages are that it does matter what language
they were written in, they provide a common object in an organisation that
can be called from any web page, they use an (almost) standard XML syntax to
call them, they don't have to exist on the same server, and finally, many
companies have them and don't want to have to rewrite the same logic in
another language. The calling web page doesn't have to know anything about
the internal logic of the web service, just the appropriate XML command.
What do I want to do with them? It can help sell PH Web if I can say to a
client that it can plug into their existing internet environment using
already established services. For example a company may have a standard web
service to verify someone's security access on an extranet. Any web page on
the company's extranet can call the same web service irrespective of the
language that page was written in (ASP, JSP, PH Web, etc)
Why can't you do that with PH Web itself? Because any company that has an
intra and/or extra net already has pages and probably web services in place
and don't want to have to rewrite common logic in PH Web. PH Web is usually
introduced in a niche application, e.g. updating a data mart, rather than
the primary web page generator. If a company must rewrite existing logic in
PH Web they will say "don't bother. I'll just do it in ASP.Net". In other
words I want PH Web to play nicely with the other kids in the playroom. :)
The interface protocol with web services, while idiosyncratic to the
application, is always done via an XML command string. Hence my suggestion
of having a "DO XMLCOMMAND ..." statement in PH Web.

Blue
