Application architecture - Flex best practices

Flex best practices – Part 2: Development practices | Adobe Developer Connection

Flex applications are complex systems that greatly benefit from thoughtful planning. Use proven methodologies to ensure the application being built is structurally sound.

Create use cases

Generate use cases for each goal or task in the application. Define the use cases from the perspective of an Actor. Typically, an Actor is simply a user of the application you are building. A use case can be created around any interaction that a user performs. Actors can also be the application itself, another application, or an outside system such as a web server.

Consider using UML

Describing the application's main classes and data model using the Unified Modeling Language (UML) can help refine the objects in your application and avoid potential rework to the code later.

Consider using code generation

There are a number of tools that will generate ActionScript 3.0 source code from UML diagrams. This can save time in some cases. Two tools worth investigating are Enterprise Architect from Sparx Systems and the free Violet ActionScript 3 Generator (VASGen).

Consider using design patterns

Two great books to have in your library are: Design Patterns: Elements of Reusable Object-Oriented Software and Head First Design Patterns.
