The Three Problems That Isolation Solved

We want to achieve repeatable read. The problem is called non-repeatable read. Phantom read is the third one which is essentially a row that is inserted because your query is unbounded. So they invented around four isolation levels to solve these problems. How about we jump into it? Hussein, where are you from? Khalid, I am from Bahrain. Move to the state in 2015. If the translation is syndrome. Sorry about that.
