Introduction

Before you start reading this article let me confirm that I am not a guru in database designing. The below 11 points which are listed are points which I have learnt via projects, my own experiences and my own reading. I personally think it has helped me a lot when it comes to DB designing. Any criticism welcome.

The reason why I am writing a full blown article is, when developers sit for designing a database they tend to follow the three normal forms like a silver bullet. They tend to think normalization is the only way of designing. Due this mind set they sometimes hit road blocks as the project moves ahead.

In case you are new to normalization, then click and see 3 normal forms in action which explains all three normal forms step by step.

Said and done normalization rules are important guidelines but taking them as a mark on stone is calling for troubles. Below are my own 11 rules which I remember on the top head while doing DB design.

在日常工作中,当我们遇到海量数据时,如何从中挑选出自己想要的数据呢?是盲目的查找,还是寻求新的解决方案亦或是通过技巧来获取?开发者在设计一个数据表单时,往往会遵循三条常用形式,他们认为常规模式是设计的唯一途径。然而由于开发者一开始就抱有这种心态,使数据表单设计变得墨守成规,阻碍了它的创新。

作者Shivprasad 从平时的工作项目中积累了一些经验,向我们介绍了11款制作数据表单技巧,当设计到数据表单制作时,不妨以此来参考,以丰富我们的应用经验。
