A data structure known as a hash table.. In computer science, a data structure is a data organization and storage format that is usually chosen for efficient access to data. [1] [2] [3] More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data, [4] i.e., it is an algebraic structure about data.
In computer programming, a rope, or cord, is a data structure composed of smaller strings that is used to efficiently store and manipulate longer strings or entire texts. For example, a text editing program may use a rope to represent the text being edited, so that operations such as insertion, deletion, and random access can be done efficiently.

This is a list of well-known data structures. For a wider list of terms, see list of terms relating to algorithms and data structures. For a comparison of running times for a subset of this list see comparison of data structures.
Here are time complexities [5] of various heap data structures. The abbreviation am. indicates that the given complexity is amortized, otherwise it is a worst-case complexity. For the meaning of "O(f)" and "Θ(f)" see Big O notation. Names of operations assume a max-heap.

A retrieval data structure can be used to construct a perfect hash function: First insert the keys into a cuckoo hash table with = hash functions and buckets of size 1. Then, for every key store the index of the hash function that lead to a key's insertion into the hash table in a r {\displaystyle r} -bit retrieval data structure D ...
However, not all persistent data structures are purely functional. [1]: 16 For example, a persistent array is a data-structure which is persistent and which is implemented using an array, thus is not purely functional. [citation needed] In the book Purely functional data structures, Okasaki compares destructive updates to master chef's knives.
