Question

Quizplus · Accepted Answer

The term "fetching" refers to the process of retrieving data from the database and loading it into the run-time memory. A "fetching strategy" is a model for specifying when and how an ORM framework retrieves persistent objects during a navigation process. Therefore, choice A is the best answer. Choice B, "navigation strategy," is not specific enough to describe the process of retrieving persistent objects. Choice C, "object permanence," refers to the ability of an object to persist beyond the scope of its creating process, and is not related to the process of retrieving persistent objects from a database. Choice D, "class navigation," does not accurately describe the process of retrieving persistent objects during ORM navigation.
