What are the advantages and disadvantages of network database model?

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.
