How Can We Represent Simple Networks?
As with trees, simple networks can also be represented using linked lists and indexes.
Linked-List Representation of Simple Networks
Consider the simple network shown in Figure H-25. It is a simple network because all of the relationships are 1:N, and the SHIPMENT records have two parents of different types. Each SHIPMENT has a CUS-TOMER parent and a TRUCK parent. The relationship between CUSTOMER and SHIPMENT is 1:N because a customer can have several shipments, and the relationship from TRUCK to SHIPMENT is 1:N because
