B-Tree

AVL Trees:

AVL tree is a self-balancing binary search tree in which each node maintain an extra factor which is called balance factor whose value is either -1, 0 or 1....

B-Tree:

A B-tree is a self – balancing tree data structure that keeps data sorted and allows searches, insertions, and deletions in O(log N)  time....

Difference between AVL Tree and B-Tree:

S.No. AVL Trees B-Tree 1 It is a self-balancing binary search tree It is a multi-way tree(N – ary tree). 2 Every node contains at most 2 child nodes In this tree, nodes can have multiple child nodes 3 It has a balance factor whose value is either -1, 0, or 1. Balance factor = (height of left subtree)-(height of right subtree) or Balance factor = (height of right subtree)-(height of left subtree) B-Tree is defined by the term minimum degree ‘t‘. The value of ‘t‘ depends upon disk block size.Every node except the root must contain at least t-1 keys. The root may contain a minimum of 1 key. 4 AVL tree has a height of log(N) (Where N is the number of nodes). B-tree has a height of log(M*N) (Where ‘M’ is the order of tree and N is the number of nodes)....
