Question

I’m starting a Flex app on a pretty big reporting engine and want to know how best to connect to a Postgres Database. I’d like to create a REST API architecture so I can use the service for more than just the Flex app(mobile possibly).

These are my options I’ve found:

Datatype: either XML, JSON or AMF

Flex Service: HTTPService or WebService

Server(using PHP): ZendAMF, custom json_encode implementation, Zend_Rest_Server

I’ve got my views all mapped out, and the api functions designed. Basically what I need is advice on which Flex / back-end service combo to provide.

Thanks for the advice!

Answer 1

Best service/connection combo for Flex/Server Implementation

There is no best way, but actually depends upon your project and how would you like to proceed. There are three ways.

1. Remoting
2. HTTP Service
3. Web Service

Since you would like to re use those services in other applications too, i would suggest you to go with Web Service. You can create your Web Service using any Server siding language which you prefer and communicate it with your Flex Application.

Regarding AMF

Its one of the ways how you can interact your Flex App with Server siding language. AMFPHP or ZendAMF does a good job and its so easy to communicate.

I would suggest you to concentrate more on Flex Architecture rather than looking into how your Flex is gonna communicate with Backend.

Check out for Modules based Architecture.
Check for which framework you are going to develop your Flex App. [ Mate, Cainogram, Swiz or someother] When you have decided with your frontend Architecture on how the flow should happen, you can then decide on how to communicate and which is the best possible approach for your project keeping the future things in your mind.

Since your Application is going to be reports oriented, go for Web Service.
