Nested Hierarchies

Nested hierarchies are organizational structures where items are grouped into categories, and these categories are contained within larger categories, creating multiple levels. Think of a library: individual books are grouped into genres (like fiction or mystery), genres are part of broader sections (like adult or children's books), and all sections are within the entire library. Each level is nested inside a higher level, helping to organize complex information or systems in a clear, logical way. This approach makes it easier to understand relationships and find specific items within a larger structure.
