The only limit is the one you set yourself.

一本书是作者和读者之间的对话，一种超越时间和空间的对话。

The database is the most important piece of software in the enterprise, and the most important piece of software in the enterprise is the database. The database is the foundation of all applications. The database is the heart of the application, and the application is the heart of the business. The key to performance is to keep the hot data in memory.

永远不要放弃你的梦想，无论它们看起来多么不可能。

有时候，只要你坚持下去，活下去，就已经是非凡的成就了。
