WebBinary Search Tree is similar to a graph but with some special properties, a BST (Binary Search Tree) has a node, left pointer and a right pointer. They allow fast lookup, addition and removal of items, and can be used to implement either dynamic sets of items, or lookup tables that allow finding an item by its key.
