This is implementation of Bayer Trees, sometime referred to as Balanced Tree and normally used for indices of data bases. These routines provide all stuff that is needed to create and destroy; insert, update and delete; load and destroy; search and traverse; check a tree.Sort huge amounts ...
Learn how to implement a B+ Tree data structure in C++ with our comprehensive tutorial. Step-by-step guide and code examples included.
从B树到B+、B*再到B-linked-tree的一些学习总结。 1 B树用阶(order)定义 Every node has at mostmchildren. Every non-leaf node (except root) has at least ⌈m/2⌉ child nodes. The root has at least two children if it is not a leaf node. ...

1. 写在前面 说起B+树,大家应该都很熟悉。B+树是一种平衡的多路搜索树,广泛在操作系统和数据库系统用作索引。相比于内存的存取速度,磁盘I/O存取的开销要高上几个数量级。而将B+树用作索引时,它可以在查找过程有效地减少磁盘I/O操作次数。 一般涉及B+Tree的书籍和文章都会提到它广泛用作外存的索引中,但是...

实际的数据库中,单个表常常会有大量的二级索引,也就是大量的B+Tree,显然对每个B+Tree分别加锁开销是很大的。Mohan C在文章《ARIES/IM: an efficient and high concurrency index management method using write-ahead logging》[11]中提出了ARIES/IM,将加锁对象由B+Tree上的Key-Value变成了其最终指向的数据,这样...
