B-Tree : B-Tree is known as self-balancing tree as its nodes are sorted in inorder traversal. A Computer Science portal for geeks. Each node of the Binary Indexed Tree stores the sum of some elements of the input array. Hash Function − A hash function, h, is a mapping function that maps all the set of search-keys Kto the address where actual records are placed. When a new record is inserted into the table, then we will generate an address for a new record based on the hash key and record is stored in that location. Therefore, we traverse at-most O(Logn) nodes in both getSum() and update() operations. The Multiple Granularity protocol enhances concurrency and reduces lock overhead. Requirements for Tree-Based Techniques A B-tree is one of the most popular methods in databases for indexing traditional data. Otherwise, we recur down to the appropriate child (The child which is just before the first greater key) of the node. Example: Searching 120 in the given B-Tree. This accentuates the significant improvement made to the search time for any given key.
