What are the drawbacks or disadvantages of the network database management system model?

What are the drawbacks or disadvantages of the network database management system model?

Drawbacks or disadvantages of the network database model

  • The network database model is very complex in their structure.
  • It is difficult to understand where the entity is connected to the other entity.
  • When creating this model the connection line of the entities are high amount which is draw too difficult in the pictorial representation.
drawback of the network data model
  • It creates so many confusion of an entity about their multiple parent connection in the structure because of their property of 1to many and many to many connections.
  • It inserts data according to pointer only.
  • It updates data according to pointer only.
  • It deletes data according to pointer only.
  • The whole data are very complex to understand if you delete any parent entity which has many parents entity has connected will lose to accessing the data in the relations.


Can a network database be a complex to understand?

Yes, it is true that the complex information can be defined in the network database model but the network database model can be a complex model due to heavy connection of entities in parents to child's or many types grand parents entities are connected to the great grand parent entity.


The image shows the diagram of connecting the greatest grand parents, grand parents, parents and child entities are connected to each other with the complex design which is difficult to understand their relationships.


There is only one entity is a single entity which is great grand parent entity in the network database model in tree like structure only.
The network database make a many relationships shows in the model gives a complex information to the users and user doesn't decide clearly the data consistency from the network database model.

I am exploring the points on if data centers uses a SAN how it is bigger than SANs?

Is data centers using a SAN and how much are data centers bigger than SANs? The data centers are used to provide the big data analytics for the website and companies to provide the processed data for making different types of informed decisions at a large amount of data processing in the data centers because it is a very big area to install into the building and many buildings if it requires to install into many buildings. The large requirement of data centers installation is necessary because the data centers uses many types of computers, storage devices, network attached storages, network devices such as:- servers, switches, hubs, routers, bridges, repeaters, gateways etc. data cables and different types of network equipment to use in the data centers to make a large area of data processing for the companies uses and major projects for website at larger industrial area for website for data processing. The storage area network is used to provide the high performance of data processing...
