脏读 dirty reads：当事务读取还未被提交的数据时，就会发生这种事件。举例来说：Transaction 1 修改了一行数据，然后 Transaction 2 在 Transaction 1 还未提交修改操作之前读取了被修改的行。如果 Transaction 1 回滚了修改操作，那么 Transaction 2 读取的数据就可以看作是从未存在过的。不可重复的读 non-repeatable reads：当事务两次读取同一行数据，但每次得到的数据都不一样时，就会发生这种事件。举例来说：Transaction 1 读取一行数据，然后 Transaction 2 修改或删除该行并提交修改操作。当 ...

男人和女人的区别
