Long,

    If your interviewing a DB designer you might want to add a question on normalization, namely how they view the process. I've seen what IMHO is both ends of the spectrum, namely every thing absolutely normalized to the N'th degree and absolutely no normalization at all. In case 1 you end up with minimal storage requirements, but kill the CPU's when you try to create information from the data. On the other end you save of CPU time, but clobber the system with disk requirements. Either extreme makes modification of the design rather painful.

Hi,

I am preparing questions for an Oracle DB Designer job interview. Two questions that I would like you to give me some input. They are

1. What are the aspects of DB Design that you would consider to be important in J2EE applications development?
2. Organisations usually have some standards for DB Design. What would your approach be to using and/or reviewing these standards?

Your comments are appreciated.

Long
