Flex makes it easy to use XML. It also makes it easy to layout an interface
and you can skin it. You can do all this in Flash, but it will take longer.
Flex has excellent support for transitions. You really need to check out
Flex.
I'm feeling guilty about banging on about flex on this list, so I probably
should stop now. Ask the same question on flexcoders.

So to create an CMS I should use Flex... But it is possible to do it in
flash too? I mean if I want to make more Interactive Interfaces, and
transitions...

You were concerned about decompilers being used to reverse-engineer the
code
and therefore compromise security. I think it's known that there are
Flash
decompilers for AS1/2. I haven't heard about an AS3 decompiler yet. If
you
compare Flex and Flash (CS3/AS3) vulnerability to decompilation, since
both
are working with thye same language I would think there's little between
them as regards susceptibility to decompilation.
IF you consider other security risks, for example interception of data
en-route to a database, there are essentially three mechanisms by which
that
can be done
1) The client passes data between the client machine and a server
(typically
via a http request of one form or another). There's no difference between
the vulnerability of Flash or Flex in this respect since both would use
the
same kind of mechanisms. Besides plain HTTP you have socket server and
proprietary formats such as AMF, but both Flash and Flex have access to
these mechanisms equally.
2) The client (Flex or Flash) can use HTTPS to encrypt the data, so
there's
little difference between Flex and Flash here.
3) Unusually a Flash or Flex client could use an SQL library to directly
make calls to a remote database. In this case the security is dependent
on
the safety of the database protocols used and the ability to reverse
engineer the application. The database is publicly exposed to allow the
clients access.
4) I understand that SQL server does allow direct XML socket access,
thereby
enabling Flash or Flex to directly access the database. This is rather
similar to 3.
So essentially there's little to choose security-wise between Flex and
Flash
CS3/AS3. The most secure model involves a good server-side component that
controls access to the database and enforces security.
In terms of a CMS application though, I think Flex wins hands down. It's
features for developing user interfaces are way ahead of Flash,
particularly
with the ability to read and manipulate XML data and generate and layout
data-driven interfaces. I know Flash now has E4x in AS3, but Flex goes
beyond that.
