An '''Object graph''' is a view of an object system at a particular point in time. Whereas a normal [[data model]] such as an [[UmlUML]] [[Class diagram]] details the relationships between objects, the object graph relates their instances. [[Object diagram|Object diagrams]] are subset of the overall object graph.

Object-oriented applications contain complex webs of interrelated objects. Objects are linked to each other by one object either owning or containing another object or holding a reference to another object. This web of objects is called an object graph and it is the more abstract structure that can be used in discussing an application's state.
