Network Database model was designed to solve some of Hierarchical Database Model. Specifically this solves the problem of data redundancy by representing relationships in terms of sets.
ADVANTAGES
- Organization: Information is grouped into entities/records and each entity has attributes, which correspond to column headings.
- Very efficient in retrieval
- Conceptually simple and easy to design
- Can handle the diverse sort of relationships (one-to-many and many-to-many relationships)
- Clear line of demarcation between programs and the complex physical storage details. Application programs work independently of the data.
DISADVANTAGES
- All the records have to maintain using pointers thus the database structure becomes more complex. Network model large number of pointers is required to insertion, deletion and updating.

What are the advantages and disadvantages of network data model?
Network data model is just like a normal database model. In network model the data is seen as related to each other by links. Or we can say the relation between the data is represented by links.
What are the examples of network database model?

Definition of network model?
A network model is actually a flexible database method of representing objects and their relationships to each other. Its graph is not restricted to a specific hierarchy. Each individual record is not restricted by a finite number of parent and child groups.
What are the advantages and disadvantages of whites communication model?
White's communication model highlights the importance of context and the interaction between sender and receiver, emphasizing feedback and the cyclical nature of communication. Advantages include its focus on clarity and mutual understanding, which can enhance effective communication. However, its disadvantages lie in potential oversimplification of complex interactions and the assumption that feedback is always provided, which may not occur in all scenarios. This model may also overlook the impact of cultural and social factors on communication.
