Definition
Noun: A hierarchical structure is a way of organizing items where each item, except the top one (the root), is subordinate to one or more other items. The items are arranged in levels, forming a structure that resembles a tree, with branches representing relationships of superordination and subordination.
Usage
This term is used to describe the organization of systems, information, or groups where elements are ranked or ordered by level of importance, authority, or inclusion. It implies a clear chain of command or a parent-child relationship between levels.
Examples

Advanced Usage
