B sharp tree

From Wikipedia, the free encyclopedia

The correct title of this article is B# tree. The substitution or omission of a # sign is because of technical restrictions.

A B# tree is similar to a B+ tree with rotations allowed among brothers only (immediate siblings).

Insertion Procedure:

Find the node where the new key is to be inserted. If that node is full we must try to perform a rotation with one of our brothers. If all of our brothers are at capacity we must split the node as we do in a B+ Tree.
