Dreamweaver cs6 suite development questions/concerns

Question

Hello,
I am new a new creative cloud subscriber. I have past experience with programming a java environments and SQL. I am new to HTML5/CSS3 and have read a book on the subject to understand the design concepts in effort to find a good environment to develop mobile applications. I like what I see using fireworks to create HTML5/CSS3 to create code for more complex objects/elements.
Additionally, watched all the videos and am ready to roll up my sleeves and get started. As I have watched the videos and goggled allot of forums regarding DM CS6 and web applications I have a few questions and concerns. I will preface this with the understanding that this involves new features/ technologies and will suffer some growing pains.
Questions/ Concerns:
1) Fluid Grid Layout tool:
Can I create a mobile application with this tool that will work on both tablets and smart phones (not desktops) compiling  a single optimized site using the phone gap tool; or do I have to create 2 separate site and compile?
2) Phone Gap
I have read that there are allot of issues with compiling applications. Even watching the adobe road show video, they could not get it to work (yikes).I have also read that I phone product code need to be compiled using xcode(tools); needed to have an apple subscription (which I have access to) What are the known issues compiling mobile applications for the different device platforms?
3) Sever-Side Mobile Applications
a) As I understand it, this cannot be accomplished with this environment without a web service that     communicates to the server-side scripting/ Database server.
b) Reading about local storage, what are the limitations and how do they effect mobile applications if there is more complex scripting and large record sets?
C) Are there ways to create user/ security roles (I would imagine the integrity issues with security would be staggering)?
4) Responsiveness
I have played around DM, I have noticed it crashing and being very sluggish. I know its not memory or processing issues as I have read several posts on the topic.
It seems that adobe is making it easier to design and develop within one product/suite. These tools seem very powerful. The direction makes sense as I like elements of both development and design. I am concerned that I will hit walls and want to avoid banging my head. I am still new to this environment and the mistakes may be mine. With that being said, do you think Adobe will get these issues resolved out and have a great environment and development model.
Thanks in advance for the light anyone can shed on these subjects as I am eager to get started (but a bit worried).

Answer 1

Hi
To add to Davids reply -
Item 3:
Are you talking about apps. or web pages on mobile devices, (they are not the same thing)?
If web pages then the server/database side is no different to a normal web page which does require a server supporting these. As for local storage, (works whilst off-line) this is normally done via javascript and a local database, but I would not use this feature for anything too complicated as the database is stored on the users computer/device, and only 'communicates' with your server/database when the user is once again on-line and connected to your web page.
As for item 3.c. - Doing this for off-line use is a complete waste of time, as the user has access to any encryption code and the database entry's, which they can then use when on-line again. A simpler solution would be to require just the users credentials and store this locally, (still not ideal, but at least all the users DB is not downloaded).
Regarding item 4. Some users have reported problems, but for me personally 99.9% of them I have not experienced with the release version of CS6, and performance issues for me all vanished when I upgraded my PC to an i7 processor with 16Gb memory, an extreme solution for many I admit, but your computers speed and memory will have a dramatic effect on the user experience.
