This innovative approach allows relationships among objects to be automatically resolved in an object-oriented relational database model. Notably, this method eliminates the need to retrieve data from the database until it is actually required. A 'fault' class is defined, along with fault objects whose data has not yet been fetched from the database. When an object that includes a relationship is fetched, fault objects are created to act as stand-ins for the destination objects of those relationships. These fault objects transform into actual enterprise objects and fetch their data the first time they are accessed. Subsequently, any messages sent to the target objects are responded to by the objects themselves.
