What are the disadvantages or drawbacks of the hierarchical database model?

What are the disadvantages or drawbacks of the hierarchical database model?

  • The hierarchical model cannot represent all the relational connectivity of the entity and their attributes of the database model.
  • It can represent only basic detail of the database model which is not proper database model.
  • When we using this model for the project demonstration it will so lengthy to make their chart of hierarchical model and covers so much space in the board, page of the document.
  • This model is not possible to create without hierarchical characters.
  • When you deleted parent entity this model is does not exist for their parent base.
  • In this model if you delete any child entity so under the deleted child entity we lose those entity which has connected to deleted child entity.
draw back or disadvantage of hierarchical mode
In this image shows the wrong way to connect the child entity on hierarchical model which makes drawback or disadvantage of the model.
  • If you create and connect the new entity to parent entity it makes massive structure and difficult to find out the connection of all entity in the model.

Can hierarchical databases model complex information to display it?

No, it is not true that the hierarchical database model cannot be able to display complex information which gives us so many types of entities and hierarchical databases include three layers easily described for a simple database model to display the small information more than the other types of database models.

this image shows how the hierarchical database model can be complex and making confusion with which entity is connected to which lower entity


The user can make a short explanation using the hierarchical database model because it is a tree-like structure to display the grand parent, parent and child entity only in the database models.
Lowest child entity only shows the description in one word, hierarchical character to store or long cannot be useful but in some cases the user includes the hierarchical in long sentence into the hierarchical database model to explain more.
