Hierarchical databases organize data in a tree-like structure with parent-child relationships and a strict one-to-many hierarchy, while network databases use a more flexible model with many-to-many relationships through pointers or links between records. Hierarchical databases are faster for accessing data along predefined paths, while network databases allow for more complex data relationships but can be more complex to manage.

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.
