Question : AIR Flex Application

I have a client who we recently developed a Flex application that allows end users to fill out an online application.  They are now interested in having us develop an internal Flex application that communicates with their existing MSSQL db. We will be using eclipse ide and the desktop application for Flex choice (Adobe AIR).  I would like to know the best way to communicate with the SQL database?  In the original app we used ASP.net to communicate back and forth passing xml.  In the new scenario they currently do not have an internal web server running,  but can if needed.    

Answer : AIR Flex Application

You could use plain old webservices which work's fine.  

You could look at: http://www.themidnightcoders.com/products/weborb-for-net/overview.html which will has faster data transfere due to AMF.

Or you could look at the ultimate Flex/Air server language ( IMO ) Coldfusion and use Flashremoting which is part of Coldfusion.

I have a link somewhere on getting Flex to communicate with .NET using linq I'll try find it.
