WebAdvantage of B+ treeindex files: –automatically reorganizes itself with small, local, changes, in the face of insertions and deletions. –Reorganization of entire file is not required to maintain performance. (Minor) disadvantage of B+ trees: –extra insertion and deletion overhead, space overhead. WebThe value of t should be at least 2. All the nodes can have at most 2 t − 1 keys. A node with n keys must have n + 1 child nodes. If a root node is a non-leaf node, it must have at least 2 child nodes. An example of a B-tree with t = 3 is given in Figure 2.

In computer science, a B-tree is a tree data structure that keeps data sorted and allows searches, insertions, deletions, and sequential access in logarithmic amortized time.
