The record that is created when a complex network is decomposed into a simple one is called an intersection record. Consider the StudentClass complex network. An intersection record contains a uniquekey from a STUDENT record and a unique key from a corresponding CLASS record. It will contain no other application data, although it might contain link fields. The general structure of this relationship isshown in Figure H-29. Assuming that the record names are unique (such as S1, S2, and C1), an instance of the STUDENT-CLASS relationship is illustrated in Figure H-30.
