BTreeInsertion(name) Here,weadd[Platt,Jenny]. From the root, [Platt, Jenny] > [Dumais, Susan], so we go to the second leaf. Since the last name Platt is already in the tree, we add [Platt, Jenny] after [Platt, John]. ...
Inserting an element into a B+ tree consists of three main events: searching the appropriate leaf, inserting the element and balancing/splitting the tree. Let us understand these events below. Insertion Operation Before inserting an element into a B+ tree, these properties must be kept in mind...
注意 BPlusTree 的开头,那儿定义了两个 using 别名方便我们reinterpret_cast的时候使用 usingInternalPage=BPlusTreeInternalPage<KeyType,page_id_t,KeyComparator>;usingLeafPage=BPlusTreeLeafPage<KeyType,ValueType,KeyComparator>; 帮助函数 另外,推荐在b_plus_tree.cpp实现一个函数GetLeafPage(),功能是根据 Key ...
5.If a parent is without m/2 nodes, then we repeat the above steps for the parent node in question. These steps are repeated until we get a balanced B tree. Given below is an illustration to delete a node from B tree. Consider the following B tree once again. ...

tree structured fileIn this paper we model the root node insertion activity of block split tree structured files such as the B-tree and its variants. Specially, we derive formulas for the events of inserting each entry into a B+ tree root node. The formulas also apply to B-trees and may...
