Introduction of B-Tree - GeeksforGeeks
Dec 28, 2023B-Tree is defined by the term minimum degree 't'. The value of 't' depends upon disk block size. Every node except the root must contain at least t-1 keys. The root may contain a minimum of 1 key. All nodes (including root) may contain at most (2*t - 1) keys. Number of children of a node is equal to the number of keys in it plus 1.

Difference between B tree and B+ tree - GeeksforGeeks
Jan 25, 2023Difference between B tree and B+ tree. B-Tree: B-Tree is known as a self-balancing tree as its nodes are sorted in the inorder traversal. In B-tree, a node can have more than two children. B-tree has a height of logM N (Where 'M' is the order of tree and N is the number of nodes). And the height is adjusted automatically at each update.

为什么 B-tree 在不同著作中度的定义有一定差别？
以下简要介绍索引与 B-tree 的关系，并尝试分析历史上不同文献间 B-tree 定义存在差异的原因。 做数据库的同学对 B-tree 一定不会感到陌生。B-tree（中文翻译为 B树 或者 B-树）是我们熟知的一个经典数据结构，它是一种平衡的多路查找树，广泛应用于计算机文件系统与数据库索引。 理解上述「费解」差异的突破口是理解设计 B-tree 的「目的」与 B-tree 的「性质」。 回顾之前总结关于 B-tree 的三个要点可以看到，设计 B-tree 的「目的」是为了减少磁盘 I/O 的次数。所有定义与实现都要为达到这个目的而考虑。 zhihu
