The hierarchical model is a restricted type of network model. Again, data is represented as collections of records and relationships are represented by sets. However, the hierarchical model allows a node to have only one parent. A hierarchical model can be represented as a tree graph, with records appearing as nodes (also called segments) and sets as edges.
Data in a DBMS (Database Management System) is typically organized in a hierarchical manner. The highest level is the database, which is divided into tables. Within each table, data is stored in rows, with each row representing a record. And within each row, data is further organized into columns, with each column representing a specific attribute or field of the record. This hierarchical structure allows for efficient storage, retrieval, and manipulation of data.
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.
Data organized in ascending or descending order is called stacking data. Stacking data is usually organized by number or by alphabet.
The relational model is a model in which data is isolated by object and foreign keys to those objects which is organized in tables with multiple columns or attributes. The hierarchical model is a model in which the data is organized in a tree structure that allows repeating information using parent/child relationships.

Numerical order.
Numerical order
ranking correct answer is numerical order
A hierarchical database model is a data model in which the data is organized into a tree-like structure. The structure allows representing information using parent/child relationships: each parent can have many children, but each child has only one parent.
ranking
Taxonomy is the term defined as concepts that can be organized in a hierarchical fashion. It helps in categorizing and structuring information or objects based on shared characteristics.
