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 is network data base?
In network database model , the records are related to each other through a link. By a link we mean that it is an association between precisely two records.
Which two layers of the OSI model have the same functions as the TCP model network layer?
physical & data link layers
Advantages of flat data model?
two main early navigational data models were the hierarchical model and the CODASYL model (network model)
What are the benefits of a hierarchical data model and network data model?
In network model of database , all data is related to each other through a link. By a link we mean that it is an association between precisely two records/data . In hierarchical model records are organized as trees rather than arbitrary graphs.
Which standardization model describes the steps that data must go through to be transmitted across a data network?
the OSI model
Difference between hierarchical and Network data module?
The hierarchical data model organizes data in a tree-like structure with a single parent for each child record. On the other hand, the network data model allows for multiple parent-child relationships, creating a more flexible and complex network of interconnected records. In the hierarchical model, relationships are one-to-many, while in the network model, relationships can be many-to-many.
What is data base model?
object-based data model seems look like an entity and attributes.
What is object base data model?
object-based data model seems look like an entity and attributes.
Which layer in the Internet model are the network support layer?
Physical, Data link and Network layers make the Network Support layers.
Which layers of the OSI model does B channel use to transfer packet data?
Network Data-link
The what layer in the OSI model arranges data into packets whereas the what layer prepares data for physical transmission?
network data-link
