GDS/Tide project represents the Data Services part of GDS
comparable to LiveCycle Data Services, which is neither open source nor free, as it provides similar features such as client container of managed entities, data paging, and integration with server components, but it is based on completely different principles:
All managed entity instances are unique in a Tide context
Tide keeps the classic three layers web architecture, when LCDS removes the service layer, and is some kind of remote JPA provider for Flex applications
Tide approach is to minimize the amount of code needed to make things work between the client and the server
principles are very similar to the ones of JBoss Seam, which is the main reason why the first integration of Tide has been done with this framework. Integrations with Spring, EJB 3 and CDI are also available
need to compile your MXML/AS sources with the granite-essentials.swc and granite.swc libraries
It's even possible to use the Tide framework if you don't use GraniteDS as the AMF remoting provider by initializing the application with the singleton Tide.
Client-side setup for remoting
initialize manually the Flex remoting channels that will be used by Tide
use the DefaultServiceInitializer component
of course don't forget to change the context root to your web app path
