How is an AVL tree different from a B-tree? Last Updated : 23 Jul, 2025 Comments Improve Suggest changes 5 Likes Like Report 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 treeIt is a multi-way tree(N - ary tree).2 Every node contains at most 2 child nodesIn this tree, nodes can have multiple child nodes3 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).
