First of all, for a teacher I'd expect rather more patience and the understanding that insulting the people that might help you isn't a great way of winning them over.
I did indeed respond to one of your questions.
Your questions are quite specific and the vast majority of flex developers won't have used your technology stack. As a newbie you have to make a start and starting with an LMS for hundreds or even thousands of users isn't ideal.
I have built several Flex front-ends for multiple users (and even a flash one that had hundreds of thousands of registered users) and none of them used your development stack.
I have either used bespoke PHP or in another case django was used. In all cases the interface has been via an XML exchange.
A lot of us are really busy and don't have time to steer a newbie from little flex knowledge to implementing a complex Flex project.
A few minutes with google seems to find results.
Thank you Pauland.
SORRY for my impatience. It was the frustration of not getting anywhere. All I need is to be pointed in the right direction and I can read my butt off. As I said in a post I don't expect to be spoon-fed.
I DO appreciate any responses of course I do especially from people within the industry that are up to their eyeballs and still trying to help in their free time.
You mention that my STACK is not commonly used or known. I will look up django now.
" interface has been via an XML exchange." - not too sure what that means - could you point me to a link to read up on that.
I have read the other links already but there are problems there, also mentioned in the comments on those posts.
btw - I went this route only because Lee Brimelow (adobe evangelist) mentioned amfphp was the way to go etc... So I thought that the Zend framework would be a great idea etc... When you say that you use custom php, I take it that you have a lot of experience and that it would be easy for you ie: a framework might be better for me as I have no experience.
Would there be any chance of seeing some of that php script??? Do you serialize the data passed from server to client - I take it that is key in the speed of all this.
1000's of users - well obviously I am interested in your experience and any time you may have to post me a quickie.
CHEERS - and I have seen at least a glimmer of light on the forum which stimulates me to keep learning.
btw - I don't think I insulted anybody, I was just expressing my frustration - and if I did, I'm truly sorry.
You mention that my STACK is not commonly used or known.
I didn't say that. Plenty of people use that stack, but there are tons of server-side solutions, so you have a smaller pool of participants.
"interface has been via an XML exchange." - not too sure what that means
The front-end communicates with the server using XML. That's all.
I have read the other links already but there are problems there
There are problems with everything.
I will look up django now.
It wasn't a recommendation. I didn't code the Django server code. I and the other developer worked on an API. I don't know Django and he didn't know flash. We just had to communicate.
There are loads of differrent technology stacks that can handle hundreds or thousands of users. Flex mostly doesn't care if you use XML as an intemediary. AMF is specific to Flash/Flex. I created my front-end using a test version of the backend using PHP and MySQL. I wrote the test backend.
The data wasn't serialised. The key to speed is how well your server can serve data to multiple online users. You may have 1,000,000 users, but what is important is how many are online concurrently at any time.
I think this project is too ambitious for you to start with.
THANK YOU VERY MUCH for taking time to answer in such a detailed way.
You are right, I alone can not deal with this project nor have I the intention to. I am merely trying to educate myself well enough to be able to delegate the project to the right people. ie: How to I outsource something I know nothing about. I see that the major solution lies on the server side as you rightly point out,
I have googled over the last few weeks and it doesn't seem to be easy.
There are mysql optimizations server details etc... I suppose I have to try and speak to a company that deals with that side of things BUT it's difficult as I reside in Valencia and there are few IT firms. I don't know if you have any firm details about the specifics.
Hardware: Maybe it's about the RAM and processing power of a dedicated server
Technology: Maybe the power lies in the hands of the guy optimizing the php calls.
If that is the case (software side php) could you please indicate what I would have to ask for in a company or freelancer.
What knowledge should I ask for? - Knowledge in waht specific area?
This will be my last post as I don't wish to wear your patience and THANKS again if you're able to post.
I can't really help you, but my advice is this.
Stop focusing on technology details. You are attempting to decide on a technology but don't really know enough about it.
Make a specification of what the LMS should do FUNCTIONALLY. Try and get a UI sketched and work out how the system should interact functionally without worrying about technology.
I would help you but I am just too busy. There are people on the flash forums that have built systems like this.
You might even decide on a Flash or, cough, HTML implementation.
You should enagage people that have done this before. Do it in stages. Have a precise idea of what you want.
Why not use an existing system?
