我不知道你申请的职位是什么，如果主要是design，考虑business and database modeling. 具体的东西就是UML或一些数据库design工具

retail和inventory方面的经验, 我确实有过一些, 我想这也是他给我interview的一个原因. 关于data modeling, interviewer会问些什么问题呢? database normalization?
UML他也问过一些, 主要是问我用过什么Diagram, 数据库的工具主要有ERWIN and TOAD, 这些我也用过. 不过从来没有参加过数据库的design.

Could you give me some detail?Could you give me some detail? Why you say the change of hardware platform would cause many migration on database migration. Could you give me some examples of oracle specific functions? I know DB2 has more datatypes than oracle. Datatype matching would definitely a problem.

说个简单的，比如oracle 里的rownum，DB2里可不是那么好实现的。

An example for possible problem caused by hardware platform change,if ur application use some bit operation (for encryption or other purpose), the present of interger in different hardware system are totally different (the high part and low part), then ur programs need to be modified accordingly.

It does exist, u can try it on AIX and Windows, you will find the difference of the present of integer. Anyway this is just a minor problem that could bother them

Actually that difference is caused by Intel and PowerPC CPU, not the OS,

I think the most challenge thing in server side development is performance tuning, sometime it is mission impossible.
