4.5 AVL Trees  A tree is said to be balanced if for each node, the number of nodes in the left subtree and the number of nodes in the right subtree differ.

1 Balanced Search Trees  several varieties  AVL trees  trees  Red-Black trees  B-Trees (used for searching secondary memory)  nodes are added.

B-Tree B-Tree is an m-way search tree with the following properties: The root is either a leaf or it has 2 … m subtrees. All internal nodes have at least [m/2] non-null subtrees and at most m non-null subtrees. All leaf nodes are at the same level; that is, the tree is perfectly balanced. A leaf node has at least [m/2] – 1 and at most m – 1 entry

A B-Tree of order 5 ORDER Number of Subtrees Minimum Maximum 3 4 5 6 …… m 2 ….. [m/2] A leaf node has at least [m/2] – 1 and at most m – 1 entry
