Incomputer science, aB-treeis a self-balancing tree data structure that maintains sorted data and allows the following operations in logarithmic time. searches, sequential access, insertions, deletions The B-tree generalizes thebinary search tree...
B - Tree Datastructure In search trees like binary search tree, AVL Tree, Red-Black tree, etc., every node contains only one value (key) and a maximum of two children. But there is a special type of search tree called B-Tree in which a node contains more than one value (key) and...
