Data types

Primitive types

Composite types

Abstract data types

Some properties of abstract data types:

Structure Stable Unique Cells per Node
Bag (multiset) no no 1
Set no yes 1
List yes no 1
Map no yes 2

"Stable" means that input order is retained. Other structures such as "linked list" and "stack" cannot easily be defined this way because there are specific operations associated with them.

Linear data structures

Arrays

Lists

Trees

Binary trees

B-trees

Heaps

Tries

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

Multiway trees

Space-partitioning trees

This is data structures used for space partitioning or binary space partitioning.

Application-specific trees

Hashes

Graphs


Bolean Formules:

  • Decision List.
  • Decision Tree.
