Hello !!! I am new in this flex tech
I have made a project in AS2 with Flash. and communicating with the data through XMLs
here is that link http://sanjoghelpline.in/Application_RWSS/default.asp
Now I have to play with large set of data with graphs, grids, different options etc on this maps. I think Flex will be best for it. it will directly connect to the database to fetch datas. I am planning to use webservice.
So I need your suggestion and tips for this. And what serverside language I should choose.
Good choice. Best you can do is making a new project with Flex Builder.
Probably you can use (parts of) your existing AS2 code (be aware of the differences with AS3).
Is there a particular reason why you want to use webservices?
If not, you can considering calling the data-XML's directly by HTTPService for example.
