Network database architecture

The network database management system also has its roots in computer science: graph theory, where there are a vast and different types of nodes and relationships connect them together. There is no specific root node in this structure. It was invented in the early 70s:

As we can see, in this structure, there are a few core datasets and there are other datasets linked with the core datasets.

This is how we can understand it:

• The main hospital is defined
• It has many subhospitals
• Subhospitals are in India and USA
• The Indian hospital uses the data in patients
• The USA hospital uses the data in patients
• The patients store is linked to the main hospital
• Employees belong to the hospital and are linked with other organizations

In this structure, depending upon the design we come up with, the data is represented as a network of elements.
