Description
This B-tree applet can simulate certain fixed sized from 2-3 trees up to 5-9 trees. B-trees only, no B+-trees.
Evaluation
Strengths: simple UI, nice animation. Weaknesses: No speed control on the animation, so it gets a bit tedious (wish it could be spead up after awhile). Nonstandard terminology (what he calls a “B-Tree of order 1” is a 2-3 Tree, usually called a “B-tree of order 3”). No explanation of what is occurring, you just see the insert/delete take place in the animation. Occasional deletion bugs (numbers don’t always disappear when they are removed).
