title: Does MySQL support data structures (such as AVL tree or Heap)?
body: <p>I have studied some data structures in Java but basically, I am a web developer and I use MySQL database in my PHP applications. I wonder if we use any data structures especially AVL tree or Heap in the web application. I do know MySQL uses its own algorithm for searching and does the time complexity it follow is of binary search tree which is O(log n)??</p>
