objectgraphとは 意味・読み方・使い方

An Object graph is a view of an object system at a particular point in time. Whereas a normal data model such as an UML Class diagram details the relationships between classes, the object graph relates their instances. 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.
