The hierarchical model uses parent-child relationships to represent data relationships. Data is organized in a tree-like structure with one root and multiple levels of child nodes. This model is effective for representing data with a clear one-to-many relationship, such as organizational structures or product categories. However, it can be limiting when dealing with data that has complex or non-linear relationships. The network model, on the other hand, can represent many-to-many relationships, but is less intuitive to navigate than the hierarchical model. The relational model uses tables with rows and columns to represent data relationships, while the object-oriented model represents data as objects with properties and methods.
