Why is Database Administration so hard? @LeighRiffel my question is : it sounds like in order for a DBA to get recognition , he has to create as many problems as possible. this kind kind of explains my experience with DBA... LOL |

Why is Database Administration so hard? "The better a DBA does their job the less visibility they have." is this good thing or bad thing for the DBA ? |

How could DBAs be more 'programmer friendly'? I don't really know/believe there are such kind of 'self learned' people who is reluctant to understand other people's point. I didn't met any though |

How could DBAs be more 'programmer friendly'? I totally agree, it is not that complex, it is about communication and relation building. so the seat arrangement seems perfect in terms of dealing with such dilemma |

Should you design the database before the application code is written? I would say this is pretty idealized approach, my experience is that drastical change happens from time to time what we need to be is to be agile and quickly adapt to new requirements and keep refactoring. |

DB2 LOAD data into table - Interpreting the error messages it is just not that 440439th row. that's why I am puzzled, but after filtering the 9th null column, we did find some record, but it is just not that row. this is exactly what I am asking for. @ChrisAldrich |

DB2 LOAD data into table - Interpreting the error messages I have added more details, all I want to know is about where is error line, so that I can take a look at the constraint. and thanks for the advice of poking around the infomation center, just wonders someone might know this for shortcut |

designing server side database to store user-specific data like the ER table you draw. I think this would useful for all SCHEMA design related questions. |

How can I improve this design? @SimonRigharts what do you mean by dynamic DDL? I didn't see that in the question |

Is database normalization dead? @sqlbattsman I agree data integrity is the king; but DE-Normalizing for performance, it is almost the case, a lot of companies are trying to turn to BIGTABLE. when you say RDBMS is not performing as well as it should be, which aspect are to be improved ? and are they related with de-normalizing ? |
