WebJan 25, 2024 · B-Tree: B-Tree is known as a self-balancing tree as its nodes are sorted in the inorder traversal. In B-tree, a node can have more than two children. B-tree has a height of logM N (Where ‘M’ is the order of tree and N is the number of nodes). And the height is adjusted automatically at each update. WebB-Tree is a balanced m-way tree that is tuned to minimize disk accesses. The node size of B-Tree is usually equal to the disk block size and the number of keys in a node depends on Key size Disk block size Data organization (keys or entire data records are store in nodes) Access paths from root to leaf nodes are small. 25 62 12 19 15 17 32 39 21 23 dicks sporting goods yoga blocks
