Big Table

Tree	Search	Insert	Delete	Main Strength
Binary Tree	`O(n)`	`O(n)`	`O(n)`	Simple hierarchical structure
Threaded Binary Tree	`O(n)`	`O(h)`	`O(h)`	Easier traversal
BST	`O(log n)` average, `O(n)` worst	`O(log n)` average, `O(n)` worst	`O(log n)` average, `O(n)` worst	Ordered searching
AVL Tree	`O(log n)`	`O(log n)`	`O(log n)`	Guaranteed balance
B-Tree	`O(log n)`	`O(log n)`	`O(log n)`	Good for storage systems
