X2O is a web-based data modeling framework for rapidly developing database-driven Flex applications.

With it, you don't need to create your own database, build stored procedures, write server-side code, or even integrate your AS3 code to data services. All of this is smartly managed by X2O. Your job is to create a data model, configure as much (or as little) as you'd like, and generate the framework. You get the code and tools you need to start building your Flex app right away.

Because it's all done over the Web, there is no installation. Simply drop a generated SWC library into your Flex project and you're ready to go. You can modify your data model and regenerate as many times as you need, making X2O an incredibly agile platform.
