              Read Uncommitted
              Dirty Reads + Non-Repeatable Reads + Phantom Reads
               No solution! it allows uncommitted data to be read. For example: suppose that at the start of the transfer transaction. Alice's account has a balance of $5000 and Bob's account has a balance of $3000. Alice's transfer transaction deducts $1000 from Alice's account
               so her account balance becomes $4000. However the transfer transaction has not yet been committed so if Bob initiates a read transaction to check his account balance he may see a balance of $4000 instead of the correct balance of $3000.
