Abstract
A method for providing stand-in objects, where relationships among objects are automatically resolved in an object oriented relational database model without the necessity of retrieving data from the database until it is needed. A “fault” class is defined, as well as fault objects whose data haven't yet been fetched from the database. An object that's created for the destination of a relationship whenever an object that includes the relationship is fetched from the database. When an object is fetched that has relationships, fault objects are created to “stand-in” for the destination objects of those relationships. Fault objects transform themselves into the actual enterprise objects—and fetch their data—the first time they're accessed. Subsequently, messages sent to the target objects are responded to by the objects themselves.
