Adobe® Flex™ Data Services 2

Adobe® Flex™ Data Services enables developers to build applications that are rich not only in terms of user interface, but also in terms of how data flows between tiers. Deployed as a standard J2EE application, Flex Data Services enhances the client-side Flex framework by providing high-performance connectivity with existing server-side data and business logic. Based on a robust messaging architecture, Flex Data Services integrates with existing common middleware and provides services that automatically synchronize data between client and server, add support for real-time data push and publish/subscribe messaging, and enable collaborative and occasionally disconnected applications.
