Explanation:
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.The network database model is built upon the hierarchical data model but not restricted to it. tead of being constrained by having to know how to go from one branch to another and then from one parent to a child to find a data element, the network database model allows each data element to have multiple parent and child records. This forms a redundant network-like structure instead of a strict tree structure. A network model sets up astructure that is similar to a mesh network topology for the sake of redundancy and allows for quick retrieval of data compared to the hierarchical model.
