Flex 4 and LiveCycle Data Service 3: Data Models, Debugging and Design Patterns
Flex 4 and LiveCycle Data Service 3: Data Models, Debugging and Design Patterns is a two-day comprehensive introduction to using LiveCycle Data Services 3 with the Adobe [Apache] Flex 4.x framework. Late in 2011, the name of Adobe Flex changed to Apache Flex when the SDK was placed into the Apache Software Foundation. Now, the SDK is truly open source with development driven by community members in a meritocracy. The official Adobe Flex courseware is used in this course because the language has not changed significantly. Android Programmers, iPad Programmers, iPhone Programmers, and HTML5 Developers can learn Flex and deploy to multiple platforms with a single set of code.
