LiveCycle Data Service 3 Beta 1 is now available on Adobe Labs.

The new model-driven development features in LiveCycle Data Services 3 offer a huge leap in productivity and ease-of-use for end-to-end applications. You start an application by creating a data model (a simple XML file) in the new "Modeler" editor that plugs into Flash Builder. From that model, you automatically generate data access logic on the server and Flex client code for working with the server code.

You can even generate much of a model by dragging existing SQL database tables into the Modeler editor. When you save the model, client code is automatically generated. When you deploy the model to the server, a fully functional Data Management Service destination is automatically generated on the LiveCycle Data Services server. You can support even the most advanced Data Management Service features just by creating and deploying a model.

Using Flash Builder with LiveCycle Data Services, you can now build simple or complex data-driven applications without writing any server-side code or configuration files. You can also take full advantage of the new Flash Builder 4 features for building the client side of data-driven applications.

I’m an Adobe writer assigned primarily to Flex Builder and the Flex SDK. I joined Adobe in October of 2007 and have spent the first few months learning and using Flex and Flex Builder.

I’ve recently completed my first Flex application, and am using this blog to write about my learning experience, and also to describe some of the concepts behind the application that make it work. Actually, these are two applications that work together, vRadio and RadioLoginDB.

These applications illustrate how to use Flex to create a master-detail application that accesses data from a PHP server, and also incorporates PHP sessions.

At the end of this posting is a list of documentation sources I used to learn how to create the applications. I also have links to the source files.

vRadio and RadioLoginDB applications

vRadio is a Master-Detail application, and corresponds to many type of applications that present stored data in a variety of presentation formats, and also provide forms for updating the data.

What is interesting about the the vRadio application is the way Flex handles XML data using the E4X format. By providing an XML feed into the vRadio application, the application displays the XML data in a tree view. When the user clicks a node in the tree, details are displayed.
