data structure


Definition: An organization of information, usually in memory, for better algorithm efficiency, such as queue, stack, linked list, heap, dictionary, and tree, or conceptual unity, such as the name and address of a person. It may include redundant information, such as length of the list or number of nodes in a subtree.

Specialization (... is a kind of me.)
external memory data structure, passive data structure, active data structure, persistent data structure, recursive data structure.

See also abstract data type.

Note: Most data structures have associated algorithms to perform operations, such as search, insert, or balance, that maintain the properties of the data structure.
