Detailed explanation-1: -The network model is a database model conceived as a flexible way of representing objects and their relationships. Its distinguishing feature is that the schema, viewed as a graph in which object types are nodes and relationship types are arcs, is not restricted to being a hierarchy or lattice.
Detailed explanation-2: -What is the Network Model in DBMS? The hierarchical model is extended in the network model. Prior to the relational model, it was the most popular model. To increase database performance and standards, the network model was devised to express complicated data relationships more effectively than hierarchical models.
