What is network model in DBMS?
network model is a collection data in which records are physically linked through linked lists .A DBMS is said to be a Network DBMS if the relationships among data in the database are of type many-to-many. The relationships among many-to-many appears in the form of a network. Thus the structure of a network database is extremely complicated because of these many-to-many relationships in which one record can be used as a key of the entire database. A network database is structured in the form of a graph that is also a data structure .

What is ndm and hdm expressing relationship in dbms?
NDM (Network Data Model) and HDM (Hierarchical Data Model) are two types of database models used in DBMS. NDM organizes data in a graph structure, allowing for complex relationships and many-to-many connections, while HDM arranges data in a tree-like structure with a strict parent-child hierarchy. Both models represent data relationships but differ in their organization and access methods, with NDM offering more flexibility in relationships compared to the more rigid structure of HDM.
