Want this question answered?
two main early navigational data models were the hierarchical model and the CODASYL model (network model)
distinguish between qualitative and quantitative model
Databases store data using any of the robust data structures for efficient management of data. They can use any of the record based logical models to represent the data. Hierarchical, Network or Relational data models.
Hierarchically designed networks can more easily be expanded to suit future needs.Hierarchical design models enhance existing bandwidth through the use of link aggregation.The hierarchical model allows for specialized functionality at each layer, simplifying device management
Answering "What are the differences with the 3 models of the Toyota the 3?"
There are three database models. The three database models are as follows : 1) relational 2) network data 3) hierarchical
tcp ip and osi are having their reference models, they are not reference models.......they are network models, defines how does a network works when data is sent from one node to another within a network.

It helps you to design a database. It is a theoretical idea of what it will be like. There are different models than can be used, such as relational or network or hierarchical. Some are better suited to some kinds of databases. Using the model helps people to design and build better databases.
