WebB-tree is a special type of self-balancing search tree in which each node can contain more than one key and can have more than two children. It is a generalized form of the binary search tree. It is also known as a height-balanced m-way tree. B-tree Why do you need a B-tree data structure? WebB-Trees are a variation on binary search trees that allow quick searching in files on disk. Instead of storing one key and having two children, B-tree nodes have n keys and n+1 children, where n can be large. This shortens the tree (in terms of height) and requires much less disk access than a binary search tree would. tours to gettysburg from philadelphiaWebdesign decisions about each layer.
