How is data organized in hierarchical data model?
The hierarchical model is a restricted type of network model. Again, data is represented as collections of records and relationships are represented by sets. However, the hierarchical model allows a node to have only one parent. A hierarchical model can be represented as a tree graph, with records appearing as nodes (also called segments) and sets as edges.

Difference between hierarchical and Network data module?
The hierarchical data model organizes data in a tree-like structure with a single parent for each child record. On the other hand, the network data model allows for multiple parent-child relationships, creating a more flexible and complex network of interconnected records. In the hierarchical model, relationships are one-to-many, while in the network model, relationships can be many-to-many.
Difference between network model and hierarchical model and relational model?
