An m-ary tree in computer science is defined as a collection of nodes normally represented hierarchically in the following manner.

- The tree is started at the root node.
- Each node of the tree maintains a list of pointers to its child nodes.
- The number of child nodes is less than or equal to m.

A typical representation of m-ary tree implements an array of m references (or pointers) to store children (Note that m is an upper bound on number of children).

An m-way search tree

a. is empty or

b. consists of a root containing b (1<=b<m) keys, kb, and a set of sub-trees, Ta, (a = 0..b), such that

- if k is a key in T0, then k <= k1
- if k is a key in Ta (0<a<b), then ka <= k <= ka+1
- if k is a key in Tb, then k > kb and
- all Ta are nonempty m-way search trees or all Ta are empty

The height of a complete m-ary tree associated with n nodes is ceiling(log_{m}n).

A B-tree of order m is an m-way tree in which

a. all leaves should be on the same level and

b. all nodes except for the root and the leaves have minimum m/2 children and maximum m children. The root has minimum 2 children and maximum m children.
