Re: Connecting remotely - multi tier

Corba? Hmmm. Will have to look into it. As for XML.... Microsoft has been
plans on using it for multi-plaform communication. This is their idea in a
nutshell.

Webservers act as the "middle tier" which applications talk to. MS is going
to wrap its COM components in XML so that way foreign hosts can interpret
the data coming in over HTTP requests. As long as the hosts can understand
XML, you can write a windows desktop app to interface with it.

And this is not just "windows desktop to other platforms". This will also
allow non-windows hosts to communicate with windows servers and desktops.
They are trying to make it work for two-way communication. I believe it is
their whole Biztalk initiative. They even have SQL Server able to return
queries in XML format as well as service queries over HTTP requests from a
webbrowser by typing the query as part of the URL.
