We know a database is one that stores data related to each other. A network database is just like network database only difference between them is, in network database records are connected by means of a link.
• LDAP (Lightweight Directory Access Protocol)
A distributed database is a database in which portions of the database are stored on multiple computers within a network. Users have access to the portion of the database at their location so that they can access the data relevant to their tasks without interfering with the work of others. A centralized distributed database management system manages the database as if it were all stored on the same computer.
world wide web (WWW) is such example as different pages are related to each other .
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.
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.ADVANTAGESOrganization: Information is grouped into entities/records and each entity has attributes, which correspond to column headings.Very efficient in retrievalConceptually simple and easy to designCan 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.DISADVANTAGESAll 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.

network model is a collection data in which records are physically linked through linked lists .A DBMS is said to be a Network DBMS if the relationships among data in the database are of type many-to-many. The relationships among many-to-many appears in the form of a network. Thus the structure of a network database is extremely complicated because of these many-to-many relationships in which one record can be used as a key of the entire database. A network database is structured in the form of a graph that is also a data structure .
A network is defined by its database. A model network begins with a solid database. The digital routes and building software in which currents are transformed is next to consider. After planning output a programmer can began building the network and testing all input.
Network Database
A database is a file. A database server is a computer that shares that file over a network.
The acronym IDMS is the initials of integrated database management system. This is a network database management system for mainframes. The model used by most is the CODASYL network model.
In OSPF, a topology database is a data structure that each router maintains to store information about the network topology within an OSPF area. It includes details such as the network links, their costs, and the routers connected to those links. This database is used to calculate the best routes for routing packets through the network.
