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.
