Consider the classed Exam (Id, ExamName, Detail_Id) and ExamDetail(Detail_Id, numOfQuestions, maxPoints, isObjective). Exam HAS-A or CONTAINS A ExamDetail.
My book says that REFRESH will refresh the associated property ExamDetail every time Exam is refreshed. What do you mean by refresh ?

Thanks.

Refresh means to pull any changes that have been made in the database into your copy of the entity. Suppose you have work that takes a minute to do. Your entity might have gotten stale in that time.
