Question

What do you mean by B+ tree? Describe some of its uses.

Answer 1

B+ tree symbolizes the way of insertion, retrieval and elimination of nodes in a sorted fashion. Each and every operation is recognized by a ‘key’. B+ tree consist of maximum and minimum bounds on the number of keys in each index segment, dynamically. All the records in B+ tree are persisted at last level, that is, leaf level in the order of keys.

B+ tree is employed to visit the nodes beginning from the root to the left or/and right sub tree. Or beginning from the first node of leaf level. A bi-directional tree traversal is probable in the B+ tree.
