Relationship of business objects to service data objects
At the technical level, the WebSphere business object model maps directly to the service data object (SDO) model: a WebSphere business graph and business object correspond to an SDO data graph and data object.
A business graph is a top-level structure that defines a single child business object which can itself contain zero or more child business objects.
Using a business graph optional. Use it to provide a change summary for applying a delta updates to hold metadata about its child business objects.
