Btree search
WebMost of the operations that are implemented on btree like search, delete, insert, max, min, etc have O(h) disk accesses where h is the height of the tree. Btree is a very wide tree. The idea behind constructing the btree by keeping the height of the tree as low as possible by attaching the maximum number of keys in a btree node. The size of the ...

Lehman and Yao showed that all the read locks could be avoided (and thus concurrent access greatly improved) by linking the tree blocks at each level together with a "next" pointer. This results in a tree structure where both insertion and search operations descend from the root to the leaf. Write locks are only required as a tree block is modified. This maximizes access concurrency by multiple users, an important consideration for databases and/or other B-tree-based ISAM stor…
WebDeletion is mostly just the reverse of insertion, but has a lot of messy special cases. As in a binary search tree, it's complicated to delete a key from an internal node; the solution is to delete a key from a nearby leaf instead. We do not implement deletion in the code below, but you can read about it in HorowitzEtAl §11.2.4. 4. Implementation WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.

This module implements a binary search tree, which is a specialized usage of a binary tree. The basic principle is that all elements to the left are less than the root, all elements to the right are greater than the root.
