Question

Explain the strengths and weaknesses of network models. How do these strengths and weaknesses explain their popularity with managerial decision making?

Answer 1

The network model is a database model imagined as an adaptable method of representing objects and their connections. Its distinctive element is that the schema, viewed as a graph in which object types are hubs and relationship types are arcs, isn't confined to being a chain of importance or grid.

The network model replaces the hierarchical model with a graph along these lines permitting increasingly broad connections among the hubs. The principle distinction between the network model from the hierarchical model is its capacity to deal with numerous to numerous connections. As such, it permits a record to have more than one parent.

STRENGTHS OF NETWORK MODEL-

The major strengths of the network model are-

1.) Conceptual simplicity-Much the same as the hierarchical model, the network model is additionally theoretically straightforward and simple to plan.

2.) Capability to handle more relationship types-The network model can deal with the one to numerous and numerous to numerous connections which are genuine assistance in modelling the genuine circumstances.

3.) Ease of data access-The information get to is simpler and adaptable than the hierarchical model.

4.) Data integrity- The network model doesn't permit a part to exist without a proprietor.

5.) Data independence- The network model is better than the hierarchical model in segregating the projects from the complex physical stockpiling subtleties.

6.) Database standards

WEAKNESSES OF NETWORK MODEL-

The major weaknesses of the network model are-

1.) System complexity- All the records are mainta8ined using pointers and consequently, the entire database structure turns out to be complex.

2.) Operational Anomalies- The inclusion, erasure and refreshing tasks of any record require countless pointers changes.

3.) Absence of structural independence- auxiliary changes to the database are extremely troublesome.

Network Models can give focal points over regular models of managerial decision making including being anything but difficult to implant in wise frameworks and gaining from the information introduced as opposed to requiring human collaboration.
