Macromedia Flex

Hey,

I’ve heard a lot about this package, so i have some questions about it:

What does it exactly do or what’s the advantage ?

Is it some programming code ? Like actionscript or how ?

Do you need some special hosting program to make it work ? ( some special webservice ? ) Or does any flash enabled browser handle it ?

I’ve seen the demo and looks nice for the Rich Internet Applications …

But is it difficult ? Do you need knowledge of ASP or JSP … ? ( i meanly know only PHP ) Does it have it’s own programming code or what …

Does it work along with Flash ? Or is it standalone program ?

Could you please explain some … or gimme some more info about it. Cuz i might wanna purchase it and learn it.

Greetz,
