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.

Hie Uma, - 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 record is a collection of fields, with each field containing only one value

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
