List of data structures

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.

Data types

Primitive types

Composite types or non-primitive type

Abstract data types

Some properties of abstract data types:

Structure Order Unique
List yes no
Associative array no keys (indexes) only
Set no yes
Stack yes no
Multimap no no
Multiset (bag) no no
Queue yes no

Order means the insertion sequence counts. Unique means that duplicate elements are not allowed, based on some inbuilt or, alternatively, user-defined rule for comparing elements.

Linear data structures

A data structure is said to be linear if its elements form a sequence.

Arrays

Lists

Trees

Trees are a subset of directed acyclic graphs.

Binary trees

B-trees

Heaps

Bit-slice trees

In these data structures each tree node compares a bit slice of key values.

Multi-way trees

Space-partitioning trees

These are data structures used for space partitioning or binary space partitioning.

Application-specific trees

Hash-based structures

Graphs

Many graph-based data structures are used in computer science and related fields:
