Chapter 1 The Right Approach to Building Applications

 

常见的错误观念，及解决方法。

• 错误：让开发人员与DBA各自为政。正确让他们有更多的观念交流。

• 错误：测试开销太大。正确：　长久眼光来看，没有测试开销更大。

• 错误：没有深入了解database都提供了什么。正确：原因可能是想着数据库的移植性，或是对db的不熟悉。

DBA Don'ts:

• No views allowed.
• No stored procedures allowed.
• No features added after version 6 allowed.
• No adoption of new features for N releases.

DBA Dos:

• Do consider the develper as someone you can teach and to whom you can pass on your database knowledge.
• Do evaluate and test new features as they come out.不要对它们放手不管。不要因为某个功能给你带来的一次坏的体验而完成放弃它。每个事物都有自己的位置，都有它存在的价值。也许（大多数是）不好的体验源自于不合适的使用它。锤子用来定钉子是个非常好的工具，但是用来拧就非常难用了。
• Do backup up(支持) your policy and procedures with factual evidence.（使用确实的证据来支持你的观点。）

Developer Dos and Don'ts

• Do not try to work around the DBAs, work with then.
• Do not assum that the DBAs are working against you.
• Do ask the DBAs to tell u why.
• Do make sure you know what you are talking about.否则，你很快会失去公信力。使用科学的方法：设定一个假设，构建测试证明（否定）此假设。确保此测试足以证明你的观点。In that fashion, you 'll have a very solid leg stand on when describing why your approach is correct.
