The DDOEditingContext is the central place for storing and managing all dataobjects, knowing about the database-contexts and providing functionality for other areas of the DDOs. But that's not the point why he gets a separate page here, this is core functionality for every ORM-tool.

Because of a request in a custom software project, we integrated a powerful solution to work with remote-objects. So yes, there are RemoteEditingContexts with serializing / deserializing all objects in the EditingContect and the best about it, you didn't need to do more then to simply switch it on. You use all the CRUD-Methods, all qualifiers and all other methods in the DDOs as in any other solution.

This RemoteEditingContext-concept is an ideal solution if you need to provide access to XML-files for a client-/server-solution.
