tree structures
Nested data organizations
Tree structures are hierarchical arrangements where elements branch from a single root into progressively finer divisions—like an inverted tree.
In computing, file systems organize folders and subfolders as trees.
Family trees map ancestry.
Organizational charts show reporting relationships.
The term appears across fields where data or relationships fan outward from one origin to many endpoints: The database uses a tree structure for efficient searching.
