是否有任何 B 树程序或站点可以直观地显示 B 树的工作原理 [英] Are there any B-tree programs or sites that show visually how a B-tree works

问题描述

我发现这个网站可以让您从 B 树中插入和删除项目，并直观地向您展示 B 树的样子:

I found this website that lets you insert and delete items from a B-tree and shows you visually what the B-tree looks like:

java b-tree

我正在寻找与此类似的其他网站或程序.该站点不允许您指定 4 阶(4 个指针和 3 个元素)的 B 树，它只允许您指定具有偶数个元素的 B 树.另外，如果可能的话，我希望能够插入字母而不是数字.

I'm looking for another website or program similar to this. This site does not allow you to specify a B-tree of order 4 (4 pointers and 3 elements), it only lets you specify B-trees with an even number of elements. Also, if possible, I'd like to be able to insert letters instead of numbers.

我想我实际上找到了一个不同的网站，但那是前一段时间了，现在找不到了.

I think I actually found a different site but that was a while ago and can't find it anymore.

推荐答案

这是一个很棒的网站，http://www.cs.usfca.edu/~galles/visualization/Algorithms.html

具有交互式 B 和 B+ 树，

Has both interactive B and B+ Trees,
