Matt,

There are three ways to connect to "data" in Flex:

1. HTTPService
2. WebService
3. RemoteObject (Java only)

An HTTPService call is as simple as specifying a URL that returns XML
data.  This could be any kind of page... a CFM, JSP, ASP... even a flat
XML file.

WebService can use any SOAP or REST web service.  These can be implemented
in any language that supports web services... Java, .NET... and of course
oru wonderful CFCs. :)

RemoteObject is used to directly call a compiled Java class that sits on
the same server as Flex.  It's very powerful because you're not using web
services as at, it's actually a binary protocol called AMF and it's
supposedly a good deal faster than web service calls as well.  However it
natuarlly imposes a lot of limitations and it's basically worthless if all
you do is write ColdFusion.

Whichever of the 3 methods above you choose, they have to connect to your
DB, pull out the data and return XML to the Flash Player client. 
WebService and RemoteObject essentially handle this for you, but if you
aren't comfortable working with them then you *could* set up CFM pages
that would spit out XML... but the power there is a lot more limited.

If you're interested in Flex, check out the Flex book by MM press and
"Essential Actionscript 2.0" by Moock.  They're both solid.  Also
tomlink.net has some good resources for some of the nuances you'll run
into when working with Flex.  And if you can afford the training from
MM... go for it.  I just finished the 3 course last week and learned A
LOT!  Also there is a useful mailing list called "Flexcoders" over at
Yahoo Groups.

Good luck :)

Sorry for the off-topic

I have been playing with flex, and one thing that is missing from my
brain is how I can connect it to a database. I presume most of the
data connection stuff is done via XML and JSP? is this correct? We
cant use our CFC's?

Are there any examples out there? I have been working through the
tutorials but the JSP files just output XML .. and I needed to know
how to actually connect to a DB

Any pointers apreciated!

Again.. sorry for OT!!
