WebMar 1, 1995 · B*-tree insertion at fUll nodes may avoid splitting by first checking neighboring nodes. Keys from the full node are redistributed to a less full neighbor. If both neighbors are full, however, the split must take place. Deletion in B+-trees, as in B*-trees, is precisely the converse of B*-tree insertion. WebMar 21, 2024 · There are three main cases for deletion operation in a B-Tree:- Case 1: The key to be deleted is the leaf node. The deletion of the key does not violate the property of the minimum number of keys a node should hold. In the tree below, deleting 42 does not violate the above properties.
