Introduction

Wherever the hierarchical database model structures data as a tree of records, with each record
having one parent record and many children, the network model allows each record to have
multiple parent and child records, forming a comprehensive graph structure. This property
applies at two levels: The schema is a generalized graph of record types connected by relationship
types (called “set types” in CODASYL), and the database itself is a generalized graph of record
occurrences connected by relationships (CODASYL “sets”). Cycles are permitted at both levels.
