Advantages of hierarchical model
- Hierarchical database model is a simple model to represent the database
connectivity of entity to entity.
- This model creates in the one direction which is straightforward top to
bottom that makes it so simple.
- It is a natural database model to represent very fast and easily.
- It is basic understanding that the model which has the project base is the
top of the head known as parent.
- In this model the parent represent the base of the project entity and the child represents the sub entity of the project and gives the basic details of
the project.
- It represents the usual method of tool to set the record relationships of

The hierarchical characters describe the data of the entity including the attributes of hierarchical database models.
The hierarchical characters are used for study for a hat type of data store or mention in the model and what types of parent entities are connected with their name inside the entity.
