Explanation

A hierarchical database is a data model in which data is stored in the form of records and organized into a tree-like structure, or parent-child structure, in which one parent node can have many child nodes connected through links.

All the information in a database is organized and structured in database tables.

These tables are stored on the hard disk of the database server.

The database tables are usually divided into columns and rows.
