can someone show a site where I can find a good video tutorial about b-trees and b + trees? Thanks
http://slady.net/java/bt/view.php?w=800&h=600 try this, this is a java applet with an example of animation for a b-tree, it’s easy to understand
B-tree applets are fairly common, for b + tree found http://www.seanster.com/BplusTree/BplusTree.html
Taking a course in algorithmic analysis regarding data structures, wikipedia is the best place to start, and actually writing and playing with a running implementation is the best way to figure it out.
Although I especially found this animation is very useful.
