ADVANTAGES Provide very efficient "High-speed" retrieval Simplicity The network model is conceptually simple and easy to design. Ability to handle more relationship types The network model can handle the one-to-many and many-to-many relationships. Ease of data access In the network database terminology, a relationship is a set. Each set comprises of two types of records.- an owner record and a member record, In a network model an application can access an owner record and all the member records within a set. Data Integrity In a network model, no member can exist without an owner. A user must therefore first define the owner record and then the member record. This ensures the integrity. Data Independence The network model draws a clear line of demarcation between programs and the complex physical storage details. The application programs work independently of the data. Any changes made in the data characteristics do not affect the application program. DISADVANTAGES System complexity In a network model, data are accessed one record at a time. This males it essential for the database designers, administrators, and programmers to be familiar with the internal data structures to gain access to the data. Therefore, a user friendly database management system cannot be created using the network model Lack of Structural independence. Making structural modifications to the database is very difficult in the network database model as the data access method is navigational. Any changes made to the database structure require the application programs to be modified before they can access data. Though the network model achieves data independence, it still fails to achieve structural independence.
