NDBMS-Network Database Management System
Database: A network databases are mainly used on large digital computers. It
more connections can be made between different types of data, network databases
are considered more efficiency It contains limitations must be considered when
we have to use this kind of database. It is Similar to the hierarchical
databases; network databases.
databases are similar to hierarchical databases by also having a hierarchical
structure. A network database looks more like a cobweb or interconnected
network of records.
network databases, children are called members and parents are called occupier.
The difference between each child or member can have more than one parent. The
Approval of the network data model similar with the esteem of the hierarchical
data model. Some data were more naturally modeled with more than one parent per
child. The network model authorized the modeling of many-to-many relationships
network model is very similar to the hierarchical model really. Actually the
hierarchical model is a subset of the network model. However, instead of using
a single-parent tree hierarchy, the network model uses set theory to provide a
tree-like hierarchy with the exception that child tables were allowed to have
more than one parent. It supports many-to-many relationships.
