A hierarchical database model is a data model in which the data is organized into a tree-like structure. The data is stored as records which are connected to one another through links.

A **hierarchical database** is a design that uses a one-to-many relationship for data elements. Hierarchical database models use a tree structure that links a number of disparate elements to one "owner," or "parent," primary record.

A DBMS is said to be hierarchical if the relationships among data in the database are established in such a way
that one data item is present as the subordinate of another one or a sub unit. Here subordinate means that items
have “parent-child” relationships among them. Direct relationships exist between any two records that are stored
consecutively. The data structure “tree” is followed by the DBMS to structure the database. No backward movement
is possible/allowed in the hierarchical database.
Thanks
